C just by looking at it

If you write -1 in exponential notation, it is e^(i*pi + i*2*pi*k) where theta = pi + 2*pi*k is the argument, k is an integer denoting the branch So taking the square root gives you sqrt(-1) = e^(i*pi/2)*e^(i*pi*k) = + or - i The -i arrises from a different branch (odd value of k) The new argument, theta_2 = pi/2 + pi*k, has been "compressed in half" compared to theta. This is different from the "convention" that sqrt(-1) = i, which probably was originally defined for the branch k=0.

Would it also be the same to take the percentage (%25) and convert to a fraction (1/4). Then you multiply the number ($35) by the denominator? So, 4 x 35 = 140. The only thing is, this would only work if the numerator was 1, because the 1 would represent the other number we know?

In beginners calculus you are introduced to functions. Square root is only a function when defined as the positive root of positive integers.

When I saw the formula I understood, it's actually quite simple

Excelente

Just asking, can't it have infinite solutions if we consider fractions? Like if 2b=a then any term in form of a/b could be x. Sorry if it's wrong though.

Can you differentiate "The First Principle" of derivatives using The First Principle and also if possible, do the same using some other method?

The question was so easy

For extra credit, what is c^5/z^5 ? Answer: Chameleon

That’s what you get when you constantly have Asians representing your country for the IMO.

Now thats much more reasonable.

it's a bit confusing when "c²/z²" is pronounced "see square over see square" in english..

Dude pls reply me ..Will it work for any quadratic equation? 😢 It's so easy for me...😊

I am two minutes in to your video and I have no f'n' clue what's going on. Maybe you posted this to the wrong channel? This says math *basics*

lmao did the comments glitch out (great video!!)

Sir pls solve the question i gave u. Pls it would mean a lot

C stands for correct

nice video

bruv literally proved 1/0 = positive infinity.

OK, so not only is bprp great at math, he is also great at interpreting poorly used language!

can anyone please answer why didnt we go for finding a-b firstand then adding (a-b) and (a+b) to find a and b?

People like using quadratic formula but i still good old factorization has more debth into it and helps much more early on like you can factorize a trigonometric function in calculus to be one variable instead of 3 4 5 6 7 variable

let f(x) be a third degree polynomial with a leading coefficient 1. there is no integer k s.t. f(k-1)f(k+1)<0. f'(-1/4)=-1/4, f'(1/4)<0. Find value of f(8).

My man does not know the quadratic formula🗣

Hi bprp so i have a question what if the number in the square root cannot be simplified like the square root of 200 what do we do do we find the decimal or we leave it as our answer

But 36 is also correct 9+25=36

cant we ues Logharithme and expenoncielle to solve this >>?

Hello. Thank you for all your work. Q: Is it possible to find such non-zero square numbers a, b, c, d, that satisfies d=1/2(a + b + c).

does x=0 really work if we expand the equation into x^x * x^3 =1 ? Cuz I thought 0^0 is 1 (using limits), and 1*0=0?

1/0 is solution of x+1=x btw 😂 1/0 is new number like imaginer 1/0 have property to absorb all number in additiion but no for k/0 k is konsntanta (1/0)+1=1/0 (1/0)+2=1/0 (1/0)+3=1/0 (1/0)+i=1/0 😂 (1/0)+infinty=1/0 too 😂 But 1/0+2/0=3/0 😂 This like You try input water in full water tank water in tank is constant when in full condition

The frustrating thing is that you can work it out from the question, it tells you they are all square numbers below, so hopefully one can figure out what a square number is. Then try adding different square numbers, youll find 9+16=25. With thousands of $ at stake why screw it up?

4:53 that’s what someone who secretly is Spider-Man would say

kind of clickbait because the answer is easy doing it the normal way (quadratic formula)

case 1 3x+4 > 0, x > -4/3 x^2 > 3x + 4 x^2 -3x -4 > 0 x < -1 or x > 4 -4/3 < x < -1 or x > 4 case 2 3x+4 < 0, x < -4/3 x^2 < 3x + 4 x^2 -3x -4 < 0 -1 < x < 4 no solution combining, -4/3 < x < -1 or x > 4

Thank you from India 🇮🇳

easy X’2 × X pour tout x = 2

You could have done it using the complex root formula. It's simple and gives you all the solutions in the complex plane.

why not just see x/y=11/10 therefore x=11 and y=10?

u can multiple by (3x+4)² on both sides

Just show the result from any calculator and move your son to another school

Great sir

It's been 33 years since I had to deal with mod. Took me back for sure!

Q1: x=-1, x=-3 Q2: no real root Q3: x=-2

If you put it into a calculator you will get an error. Unfortunately sometimes though the calculator will say infinity which isn't right either but that is likely because it is calculating division as repeated subtraction

As a non native english speaker, the hard part is figuring wtf is the wording in this question
