Question

(-3)^m+1*(-3)^5=(-3)^7
​

Answer 1

Answer:

3m*3*-3power5=-3power7

m+6=7

m=1

Answer 2

Answer:

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

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

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

$by \: equating \: the \: bases$

$m + 6= 7$

$m = 7 - 6$

$m = 1$
