Question

How do you simplify `(xy) ^-1`?

Answer 1

See the simplification process below:

Explanation:

To simplify this express use these two rules for exponents:

`y - color(red)(2) = 1/2x - 2`

`a^color(red)(1) = a`

`(xy)^color(red)(-1) -> 1/(xy)^color(red)(- -1) -> 1/(xy)^color(red)(1) -> 1/(xy)`
