Question

How do you simplify `z^(-2/7) * z^(3/7)`?

Answer 1

See the entire solution process below:

Explanation:

Use this rule of exponents to simplify this expression:

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

`z^color(red)(-2/7) * z^color(blue)(3/7) = z^(color(red)(-2/7) + color(blue)(3/7)) = z^(1/7)`
