What is the answer ? Help pls

Answer 1

Answer:

B. 4

Step-by-step explanation:

Given,

${x}^{8} = {( {2}^{2} )}^{4}$

Since,

${ ({a}^{x} )}^{y} = {a}^{xy}$

Then,

$= > {x}^{8} = {2}^{2 \times 4}$

$= > {x}^{8} = {2}^{8}$

(Since the exponents are same so the bases will be also same)

Therefore,

=> x = 2

As per condition,

${x}^{2}$

(Putting value of x = 2)

$={2}^{2}$

= 4 (Ans)
