Answer 1

Answer:

X = 3

Step-by-step explanation:

${( \frac{ - 8}{11} )}^{16 - 2x} = {( \frac{ - 8}{11} )}^{10}$

As bases are same so power should be equal

$16 - 2x = 10$

$16 - 10 = 2x$

$6 = 2x$

$\frac{6}{2} = x$

$3 = x$

Answer 2

a^m / a^n = a^(m-n)

Therefore

LHS
(-8/11)^(16-2x)


Now if in LHS and RHS
Bases are equal powers are also equal

Equating powers
16-2x = 10
16-10 = 2x
6 = 2x
x = 3
