Answer 2

➡️Answer

$Value \: of \: m = 1$

➡️ Step By Step Explanation

${( - 3)}^{m + 1} \times ( { - 3)}^{5} = {( - 3)}^{7}$

${( - 3)}^{m + 1 + 5} = {( - 3)}^{7}$

$We \: Know \: The \\ Exponential \: Law$

$< / p > < p > {a}^{m} \times {a}^{n} = {a}^{m + n}$

${( - 3)}^{m + 6} = { - 3}^{7}$

$m + 6 = 7$

$m = 7 - 6 m = 1$

$m = 1$

$Therefore$

$Value \: of \: m = 1$
