If f (x) = 8^x, find the value of f (2/3).

4

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
