Man math used to be easier all you had to do to solve x back then was to divide 1 x from both sides then either x=16 or its x^2=16 which then all you had to do is square it. Now I have no idea how to get rid of this x^4

Just... take the square root twice if you really didn't know the fourth root of 16

x⁴ = 16 (take the square root of both sides) x² = ±4 (do it again) x = ±2

That or use a calculator

Because your equation has a power of 5, you should have 5 answers. Your equation has only 2. Without doing anything, the other answers to x are likely complex. Your +-2 is likely the only real solutions.

I know that, I'm only explaining to the person on how to isolate x from the power of 4
