If you have to do radicals find the prime factorization of the number then pull out groups equal to your power. Everything that comes out multiply everything still inside multiply. Easy. Definitely will help especially when you get to logs and things
Well, I did a different calculation, but it still works. Four is correct because 4x4= 16! 16x4=64. 64-11= 53, therefore 4 is the cube root minus eleven of 53!
A simply wrong method to solve these equations. But wont actually matter since no one who uses math would be mislead, but anyways; this way of content creating is dirty.
@@erwinf4311 That’s an arbitrary restriction you’re setting, video has no definition on x being strictly real, and real numbers are just a special case of complex numbers anyway
That's one of the three solution values
there are 2 more solutions:
-2-2sqrt(3)i and -2+2sqrt(3)i
Yes came to say that
I guess we're working in the real numbers
Thank you
Huh
@@frommarkham424orher possible values for x
I have never understood why math in usa is like that; you’re substracting two sides, when you’re only gonna use 1
Please elaborate, why he is only using one side. He just solves for x.

how did you get number 4?

4 is the correct answer
I got x=24
I'm not good at maths I'll see this and be like 🥴 even tho it's simple 😅
Yo I’m in year 8 and I don’t understand…
Should I understand???
X is also root 8
No it’s literally not
Would be sqrt(16) but thats just 4
Gosh this reminds me of just how much I love math
yeah but this only works on numbers with square/cube roots
Or you have a calculator, or you just write it as a square root.
Like you need help for that 😂 I will never ever mess that up in my dreams of dreams
Or just do 53+11😂
That doesn’t solve for x though. That’s x^3

What do you mean this is a "wrong" method, there is no wrong method in math as long as it works
@@MierePC It didn't work.
@@MierePC A cubic equation has 3 roots so technically it's wrong but no one cares about the other two values of x 🙂
This is middle school level. Its only with real numbers. In their tests the other two values aren’t necessary
I knew that 🧐
Then you simply know no math.
Very wrong man x3 means there could be 3 solutions and you get 4 so you’re missing 2
Nope he’s right
The 3 means the x is multiplied on itself 3 times
Yes exactly
And the two other solutions are not in R

Noob level
Soooooo. 4 minus 11 equals to 53 right?
Mathematics in a nutshell
4 cubed, u forgot the small three
4 cubed, which is 64
Very good sir mujhe bhi support kijiye
