# 1–40 Evaluate the integral. ∫ 2 x x d x

To determine

To Find: 2xxdx

Explanation

Look at the integrand in which the derivative of x is 12x . Substitute x=t and differentiate it with respect to x to get 12x=dt.

After substitution, the integral reduces to

2xxdx=2t×2dt=22tdt=2×2tln(2)+C

Finally, use back substitution that is substitute t=x to get the answer in terms of the original variable x
