integral from 0 to 2 of (e^x)^2

\int_{0}^{2} (e^{x})^{2} d x

\frac{e ^{4} - 1}{2}

Decimal

26.79907 \dots

Solution steps

\int_{0}^{2} (e^{x})^{2} d x

Apply u-substitution

= \int_{1}^{e^{2}} u d u

Apply the Power Rule

= [\frac{u ^{2}}{2}]_{1}^{e^{2}}

Compute the boundaries:

\frac{e ^{4}}{2} - \frac{1}{2}

= \frac{e ^{4}}{2} - \frac{1}{2}

Simplify

= \frac{e ^{4} - 1}{2}
