Use laws of exponents to simplify inside the parentheses of the given expression ((a ^ - 2 * b ^ 2)/(a ^ 2 * b ^ - 1)) ^ - 3
Answers: 2
![[\frac{(a^{-2}*b^{2})}{(a^{2}*b^{-1})}]^{-3}=(a^{-2-2}*b^{2+1})^{-3}\\\\\\=(a^{-4}*b^{3})^{-3}=(a^{-4})^{-3}*(b^{3})^{-3}\\\\=a^{-4*-3}*b^{3*-3}=a^{12}*b^{-9}\\\\=\frac{a^{12}}{b^{9}}](/tpl/images/0538/1313/93fed.png)
