Answer 1

mark it as brainliest.....

Answer 2

Answer:

${9}^{m} \div {3}^{ - 2} = {9}^{4}$

$( {3}^{2})^{m} \div {3}^{ - 2} = ({3}^{2})^{4}$

${3}^{2m} \div {3}^{ - 2} = {3}^{8}$

${3}^{2m - ( - 2)} = {3}^{8}$

${3}^{2m + 2} = {3}^{8}$

$2m + 2 = 8$

$2m = 8 - 2$

$2m = 6$

$m = \frac{6}{2}$

$m = 3$
