integral from 0 to 1 of xsqrt(75x^2+25)

\int_{0}^{1} x 75 x^{2} + 25 d x

\frac{35}{9}

Decimal

3.88888 \dots

Solution steps

\int_{0}^{1} x 75 x^{2} + 25 d x

Apply u-substitution

= \int_{25}^{100} \frac{u}{150} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{150} \cdot \int_{25}^{100} u d u

Apply the Power Rule

= \frac{1}{150} [\frac{2}{3} u^{\frac{3}{2}}]_{25}^{100}

Compute the boundaries:

\frac{1750}{3}

= \frac{1}{150} \cdot \frac{1750}{3}

Simplify

= \frac{35}{9}
