Evaluate ∫20(x3+x2)dx.

A.

4(5/6)

B.

6(2/3)

C.

1(5/6)

D.

2(5/6)

Correct Answer: 6(2/3)

Explanation

2, 0(x3 + x2)dx = ∫2, 0(x4/4+x3/3) = (24/4+23/3) - (04/4+03/3) = (16/4+8/3) - 0 = 80/12=20/3 or 6(2/3)

2, 0(x3 + x2)dx = ∫2, 0(x4/4+x3/3) = (24/4+23/3) - (04/4+03/3) = (16/4+8/3) - 0 = 80/12=20/3 or 6(2/3)
