Answer 2

Answer:

${( - 3)}^{m + 1} \times {( - 3)}^{5} = {( - 3)}^{7} \\ {( - 3)}^{m + 1} = \frac{ {( - 3)}^{7} }{ {( - 3)}^{5} } \\ \boxed{ \underline{ \underline{ Note}}: \color{red}{ \frac{ {a}^{m} }{ {a}^{n} } = {(a)}^{m - n} } } \\ {( - 3)}^{m + 1} = {( - 3)}^{7 - 5} \\ {( - 3)}^{m + 1} = {( - 3)}^{2} \\ \boxed{ \underline{ \underline{ Note}}: \color{red}{If \: \: {a}^{m} = {a}^{n} , \: \: then \: \: m = n}} \\ m + 1 = 2 \\ m = 2 - 1 \\ \boxed{ \color{red}{ m = \underline{ \underline {1}}}}$
