Question

(-2) power x+1 (-2) power 5 = (-2) power 7​

Answer 1

Answer:

$- 2 ^{x + 1} \times - 2^{5} = - 2 ^{7} \\ (a ^{m} \times a ^{n} = a ^{m + n} ) \\ - 2 ^{x + 1 + 5} = - 2 ^{7} \\ - 2 ^{x + 6} = - 2 ^{7} \\ if \: base \: on \: both \: sides \: are \: equal \: then \: there \: powers \: must \: be \: equal \\ now \: take \: the \: powers \: only \: and \: simplify \: it \\ x + 6 = 7 \\ x = 7 - 6 \\ x = 1$

now the answer is 1

Hope it helps you dude
