Which means that, D is the smallest because it's corresponding side is the smallest of the 3.
It would be D, E, F, because smallest to largest is 28, 32, and 34.
Hope that helps.

Expanding 8x^3, we multiply 8*8 and x^3 by x^3 to get 64x^6. Since we know that the cube root of 64 is 4, we can separate that. Next, since you add exponents while multiplying, 6/3 is the exponent for the cube root of x^6=x^2. Therefore, your answer is 4x^2
