The directions say simplify. I didn't know how to type this so over means like a fraction and the brackets should cover both upper and lower numbers. {-3(a^2b^-1)^3}^-2 over {7(a^-5b^6)^-1}

    Is this it? \[\frac{[-3(a^2b^{-1})^3]^{-2}}{7(a^{-5}b^6)^{-1}}\]

    No the brackets are over the bottom too so that the whole fraction is to the ^-2

    Ok so \[[\frac{-3(a^2b^{-1})^{3}}{7(a^{-5}b^6)^{-1}}]^{-2}\]

    So start with what's inside the brackets. Specifically work on the numerator. What do you have when you evaluate \[(a^2b^{-1})^3 = ?\]

    Correct. Now the denominator.

    \[(a^{-5}b^6)^{-1} = a^{\text{-5 * -1}}b^{\text{6*-1}}\]
