    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
