See a solution process below:

Explanation:

First, use this rule for exponents to rewrite the expression:

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

10^color(red)(-1) => 1/10^color(red)(- -1) => 1/10^1

Then, use this rule of exponents to simplify the denominator:

a^color(red)(1) = a

1/10^color(red)(1) => 1/10

1/10 => 1" tenth " => 0.1
