Question

[x^(-2)]^2 how do you simplify

Answer 1

`(x^2)^2=x^4`

Explanation:

Because of the power of a power property states that
`((x^n)^m)=x^{n*{m}}`, where n and m are real numbers, then, the expression you have just posted can be simplified by applying this property to
`(x^2)^2=x^(2*2)=x^4`.
