Question

Find the value of k if (-2)k × (-2)3 = (-2)7

Answer 1

Step-by-step explanation:

(-2)k × (-2)³ =(-2)7

(-2)k+3 =(-2)7

k+3=7

k= 7-3

k=4

Answer 2

$\mathtt\pink{SOLUTION:-}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\mathtt\purple{(-2)k × (-2)3 = (-2)7}$

$\mathtt\purple{-2k × - 6 = - 14}$

$\mathtt\purple{12k=-14}$

$\mathtt\purple{k= \frac{ - 14}{12} }$

$\mathtt\purple{k= \frac{ - 7}{6} }$
