Answer 1

10.

$8x^{-3}^{}=\frac{8}{x^3}$

11.

$5^{-3}\cdot m^6=\frac{1}{5^3}m^6=\frac{m^6}{5^3}^{}$

12.

$\frac{7p^5}{p^{-1}}=7p^{5-(-1)}=7p^6$

13.

$\frac{10t^{-5}}{t^{-2}}=10t^{-5-(-2)}=10t^{-3}=\frac{10}{t^3}$

14.

$\frac{15d^4}{3d^9}=5d^{4-9}=5d^{-5}=\frac{5}{d^5}$

15.

$6w^{-2}\cdot4w^2=\frac{6}{w^2}\cdot4w^2=6\cdot4=24$
