Step-by-step explanation:

9m \div  {3}^{ - 2}  =  {9}^{4}  \\ 9m \div  \frac{1}{ {3}^{2} }  =  {9}^{4}  \\ 9m \times  {3}^{2}  =  {9}^{4}  \\ 9m \times 9 = 9 \times 9 \times 9 \times 9 \\ 9m =  \frac{9 \times 9 \times 9 \times 9}{9}  \\ 9m = 9 \times 9 \times 9 \\ m =  \frac{9 \times 9 \times 9}{9}  = >  m = 81
