Question

How do you simplify `(3x)^-1`?

Answer 1

See the entire simplification process below:

Explanation:

First, use this rule of exponents:

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

`(3x)^color(red)(-1) = 1/(3x)^color(red)(- -1) = 1/(3x)^1`

Now, use this rule of exponents to complete the simplification:

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

`1/(3x)^color(red)(1) = 1/(3x)`
