If (x^²)^²= 16, what is the value of x?

Well, (x^2)^2 becomes x^4.

x^4 = 16

Take fourth root on both sides of the equation.

4root{x^4} = 4throot{16}

x = 2, x = -2

There are two values of x because I had to take the fourth root. If the fourth root was the given problem, then x = 2.

Is this a good explanation?

Yes, good. If you ever get to complex numbers you will discover there are also 2 complex values that work.

I will post complex numbers in due time. Math is the only subject that keeps my brain cells alive.
