Question

What is the answer ? Help pls

Answer 1

B. 4

Explanation:

Given,

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

Since,

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

Then,

`= > {x}^(8) = {2}^(2 * 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)
