do you mean this:

(2^3 - 3)^2 ?

If so

2^3 = 2x2x2 = 8 So:

(8 - 3)^2

since 8-3 = 5 you have:

(5)^2 = 5x5 = 25 and done

(2³ - 3)² = (8 - 3)² = 5² = 25

2 to the third is 8
-3 = 5
5 to the 2nd power is 25

Do the calculation in parentheses first:2³ -3 = 8-3 = 5.
Now square: 5²=25.

its 25 because:

2 to the 3rd power is 8-3 is 5 and 5 to the 2nd power is 25
(order of operations)
parentheses and then exponents

In a fractional exponent, the numerator is a power and the denominator is a root. So 32 to the 2/3 power means either the cube root of (32^2) or the (cube root of 32)^2 I usually take the root first since it make the number "smaller". The cube root of 32 = 2(cube root 4) If we squar the result, we get 4(cube root 4)^2 = 8cuberoot2. With the other method you could square first and get the cube root of 2^10. Then simplifying we would still get 8cuberoot2
