Evaluate ∫1 0 4x−63√x2−dx

A.

- 5/8

B.

-8/5

C.

8/5

D.

5/8

Correct Answer: -8/5

Explanation

1 0 4x − 63√x2 dx =∫1 0 4x − 6x(2/3) dx =(2x2−(8x5/3)/5)1 0 =(2(1)2−(18(1)5/3)/5)−(2(0)2 − (18(0)5/3)/5 = - 8/5 - 0 - 8/5

1 0 4x − 63√x2 dx =∫1 0 4x − 6x(2/3) dx =(2x2−(8x5/3)/5)1 0 =(2(1)2−(18(1)5/3)/5)−(2(0)2 − (18(0)5/3)/5 = - 8/5 - 0 - 8/5
