integral from 1 to e of ((3+ln(x))^2)/x

\int_{1}^{e} \frac{( 3 + ln ( x ) ) ^{2}}{x} d x

\frac{37}{3}

Decimal

12.33333 \dots

Solution steps

\int_{1}^{e} \frac{( 3 + ln ( x ) ) ^{2}}{x} d x

Apply u-substitution

= \int_{3}^{4} u^{2} d u

Apply the Power Rule

= [\frac{u ^{3}}{3}]_{3}^{4}

Compute the boundaries:

\frac{37}{3}

= \frac{37}{3}
