Question

find M so that (-3)m+¹*(-3)⁵=(-3)⁷​

Answer 1

Answer:

${( - 3)}^{m + 1} \times {( - 3)}^{5} = {( - 3)}^{7} \\ {( - 3)}^{m + 1 + 5} = {( - 3)}^{7} \\ m + 6 = 7 \\ m = 1$

Answer 2

Answer:

m=1

Step-by-step explanation:

(-3)^m+1×(-3)^5=(-3)^7

a^m×a^n=a^m+n

(-3)^m+1+5=(-3)^7

(-3)^m+6=(-3)^7

since bases are same, equate the powers

m+6=7

m=7-6

m=1
