Answer 1

\[(a^2b^3)(ab)^-2= \frac{a^2b^3}{(ab)^2}\]

Answer 2

Note:
\[x^{-n}= \frac{1}{x^n}\]

Answer 3

\[(a^2b^3)(ab)^{-2}= \frac{a^2b^3}{(ab)^2}\] \[= b\]

Answer 4

why is it b though???

Answer 5

\[(a^2b^3)(ab)^{-2}= \frac{a^2b^3}{(ab)^2}= \frac{a^2b^3}{a^2b^2}=b\]

Answer 6

\[Note:(ab)^2=a^2b^2\]

Answer 7

OH!!!! Okay,thanks!! Your fantabulastic :)

Answer 8

\[\frac{a^2}{a^2}=1 \ \ \frac{b^3}{b^2}=b \]
