Question

How do you simplify `(y^-3)^-4`?

Answer 1

See a solution process below:

Explanation:

Use this rule of exponents to eliminate the parenthesis:

`(x^color(red)(a))^color(blue)(b) = x^(color(red)(a) xx color(blue)(b))`

`(y^color(red)(-3))^color(blue)(-4) => y^(color(red)(-3) xx color(blue)(-4)) => y^12`
