integral from 1 to e^2 of (ln^2(x))/x

\int_{1}^{e^{2}} \frac{ln ^{2} ( x )}{x} d x

\frac{8}{3}

Decimal

2.66666 \dots

Solution steps

\int_{1}^{e^{2}} \frac{ln ^{2} ( x )}{x} d x

Apply u-substitution

= \int_{0}^{2} u^{2} d u

Apply the Power Rule

= [\frac{u ^{3}}{3}]_{0}^{2}

Compute the boundaries:

\frac{8}{3}

= \frac{8}{3}
