Answer 1

$</p><p>{\huge {\overbrace {\underbrace {\purple { Answer }}}}}$

${4}^{3} \times {4}^{7 + x} = {4}^{8}$

${4}^{x + 10 } = {4}^{8}$

bases are same so we equate powers

$x + 10 = 8$

$x = 8 - 10$

$x = - 2$

hope it helps you......

Answer 2

Answer:

HEYA BUDDY...!!

4^3 × 4^(7+x) = 4^8

=> 4^(7+x) = 4^8 / 4^3 = 4^5

=> 7+x = 5

=> x = -2
