Huh. I would have said the problem was line 3, since square root of 1 has too possible answers, so the correct substitution should have been |1^0.5|, not simply 1^0.5.

I understood all of that and somehow still don’t understand why step 4 to step 5 doesn’t work

Area of sector is similar to area of triangle or maybe special case of it Who agree with me?

Watching a guy do math without any mistakes is so entertaining bro.

How come at the last method you don't put the 5th root of 4 on the bottom denominator?

26 single digit is always 6 not matter the power, the 4 is the tricky one because it alternated between 4 and 6 with 4 making the number divisible by 5, we can see that even power of 4 is 6 whilst odd is 4( i.e. 4^2 is 16, 4^4 is 256 etc.., 4^1 is 4, 4^3 is 64, 4^5 is 1024, etc...) therofore the single digit for 4^8 is 6 making for 6+6 which the single digit is 2 which is not divisiable by 5.

Can someone solve this for me There are 3 kinds of bananas red, green, and blue. For every 4500 red bananas sold you get 1500 dollars, for every 3000 green bananas sold you get 1000 dollars, and for every 2500 blue bananas sold you get 2500 dollars. Now, for every 100k bananas sold you'll gain 1% more money(multiplicative). If I want to sell 50 million bananas of each kind, which banana color gives me more money?

(-i)^2 = -1 = i^2

I check wit intervals, the interval (-∞,-1) both absoluts values their negative inside and gives x=-1 but -1 its not on (-∞,-1) (Actually you can include -1 since 0=-0 but well I realized later) Then [-1,5) And you get the negative inside from x-5 but the positive from x+1 You get -x+5+x+1=6 that give us 6=6 so, al the values between [-1,5) its an answer (in this part was when I realized that 0=-0) And the las interval was [5,∞) That make the both positives than give us x=5 So [-1,5)U[5]=[-1,5] I didn't check if there are complex solutions

again

If its not could you explain me how to do it and how does it work

Mr is |x-6| + |x(-1)| equals to -2 and 6

Isnt that basic 8 grade but with difference i mean the In? Im sorry , correct me if im wrong cause we did the same as that just not In

When I read this my first thought was does it matter if they all read the same paper or distinct papers? I’m not smart enough to tell though

So this only works when the two "fixed points" are exactly 6 apart?

To be honest I do think Meghan Markle is suffering a bit. But it is mostly by her own doing. 🤷🏼‍♂️

The dude did not know how square roots work

Anything divided by zero is 1. That's how mathematical functions still work even with a division by zero. I needed that for my high school diploma.

Can you please make a video on Lagrange interpolation please please please

Brilliant explanation. I'm so jealous of kids today -- and teachers today! -- who can get these great explanations and learning methods at home for free. This geometric demonstration reminded me of 3blue1brown's geometric treatments of linear algebra. So cool.

Vwry interesting... In school days, I always confused why those are not same.

Anyone remember when 1+1=2 Those were the days

My markers dissapeared, I wonder who took them 💀

Chuck Norris can divide by zero

I understand easily with powers like 2^0.2 or 2^1/5

Your multiplication signs are so tiny

Infinite ♾️ hoga

I'm gonna be like say it before watching the video Is it ln? you can use to make the numbers easier to solve

My older brother wrote this on the white board and told me to solve it. For contex, I am a fifth grader. Edit: computer olympiad

1:50 no, it can't, because each student reads 5. It can only satisfy 12. (and technically not even that but the math still works) so if I newspaper can satisfy 12 then 25 can satisfy 300.

Why can x not be 0? If we divide by 0 on the very first equation top left then we get 0 is bigger than negative infinity. And with the equation at the top right, we get infinity is bigger than 0. So why doesn't that work?

when our teacher taught us about complex numbers, he used √-1 to explain the concept, and immediately warned us that we cannot write it down because it allows you to say anything is equal to anything. you just cannot write it down if doing proper mathematics. I find it funny how so many people can get it wrong.

This reminds me of the property of an ellipse. If the right-hand side of the equation is something more than 6, the solution forms an ellipse with its focus at -1 and 5 respectively, where the vertical axis is the imaginary number axis.

I always see the thumbnail of your videos and think I know the correct answer, but realize I don’t when I watch the video.

for the left ineq>1, 3X+4 must >0 because x^2>0 , so just indictical to the right ineq with additional condition: 3X+4>0, its much easier to understand

But he doesn't give a logical reason why you can't. Math is a pure logic science, everything in it 'should' be able to be proven to be true given everything that has been proven true in the past. That being said, number 2 is also wrong since ironically 1+1=2 has never been proven.

You should say from beginning specify if you are working in C or in R . It's possible to solve it in C like that but not in R .

√(-1) don't exist because it's a negative number

Wait so i literally solved it in 2 secs? And it was correct? I am not joking i just looked at 6+7 = 4913 Saw that 7^2 = 49 and that 6+7 = 13 Just assumed the same for the last and did it in 2 secs

im a french student and its pretty funny bc you guys do the "sign table" in a completly different method than in france! and btw in what grade do you learn this ?`

I feel stupid for not knowing this method that i was never taught ):

Can someone explain "the definition" in between steps 7 and 8, because I can't recall any definitions where a number to an even power doesn't have a positive value

You are now 29 years old I have approximately calculated the year you published the video (2013) and subtract 5 years from 2000 (1995) = 1995 + 2024 = 2029 ~ 29 (maybe you are 35)

isn't the frst mistake from (2) to (3)? sqrt 1 isn't just 1 it's 1 or -1 so 2 =1 + |sqrt 1|

use graphic go brrrrrrr

When you said “it’s not all real numbers”, I thought you meant complex solutions as well. Thinking about the standard norm in the complex plane, I saw that all solutions form an ellipse around the foci -1 and 5 (flat line since the sum of distances is 6). Looking at the comments, I’m not the only one to have noticed this, but still thought it was really neat.

1 divided by 0 is 1. This is a logical and question that can go beyond to a discussion of binary and even metaphysics

Pls what if you r given a²+b²?

2^2 × 2^2
