Question

How do you simplify `5/(z^-3` and write it using only positive exponents?

Answer 1

See a solution process below:

Explanation:

Use this rule of exponents to simplify and eliminate the negative exponent:

`1/x^color(red)(a) = x^color(red)(-a)`

`5/z^color(red)(-3) = 5z^color(red)(- -3) = 5z^color(red)(3)`
