Step-by-step explanation:
This is a substitution question
So we will have to substitute the value of x given into the given question
f (x) = 8^x
And x is given as 2/3
So let's get to work
8^2/3 which means that cube root of 8 then square the answer
(3√8) ^2
Cube root of 8 is 2
So we will have to square 2 to get 4
Therefore the final answer is 4
