Hi...☺

Here is your answer...✌

${9}^{2x} \div {9}^{ - 5} = {9}^{13} \\ \\ {9}^{2x - ( - 5)} = {9}^{13} \: \: \: (since \: {a}^{m} \div {a}^{n} = {a}^{(m - n)} ) \\ \\ {9}^{2x + 5} = {9}^{13} \\ \\ On \: equating \: power \: of \: 9 \: \\ We \: get ,\\ \\ 2x + 5 = 13 \\ \\ 2x = 13 - 5 \\ \\ 2x = 8 \\ \\ x = 4$
