Answer 1

$\huge\sf\green{Answer}$

$\boxed{m = 1}$

$\huge\sf\pink{Explanation :}$

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

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

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

➣$(m \: + 1) - 7 = - 5$

➣$(m + 1) = - 5 + 7$

➣$(m + 1) = 2$

➣$m = 2 - 1$

➣$m = 1$

Answer 2

Answer:

1

Step-by-step explanation:

Since the base is same the powers can be equated.

therefore, m + 1 + 5= 7

                 m +6 = 7

                 m=7-6

                 m=1
