Answer 1

When the exponent is negative, you need to move it to the other side of the fraction to make the exponent positive.

For example:

$x^{-3}$ or  $\frac{x^{-3}}{1}=\frac{1}{x^3}$

$\frac{1}{y^{-7}}=\frac{y^7}{1}$  or  $y^7$

$\frac{1-2}{3^{-3}}$     Move $3^{-3}$ to the other side of the fraction to make the exponent positive

$\frac{(1-2)3^3}{1}$  or (1 - 2)(3³)

(1 - 2)27    Simplify what's in the parentheses

(-1)27

-27     Your answer is the 1st option
