Question

Find ( m) so that (-3) to the power m+1*(-3) to the power 5=(-3) to the power 7​

Answer 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

m+6=7

m=1

Answer 2

$\huge{\underline{\mathtt{\red{S}\pink{O}\green{L}\blue{U}\purple{T}\orange{I}\pink{O}\red{N᭄}}}}$

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

${a}^{m} \times {a}^{n} = {a}^{m} + n$

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

$m + 6 = 7$
