integral from 1 to sqrt(2 of)(x^3+6x)

\int_{1}^{2} (x^{3} + 6 x) d x

\frac{15}{4}

Decimal

3.75

Solution steps

\int_{1}^{2} x^{3} + 6 x d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{1}^{2} x^{3} d x + \int_{1}^{2} 6 x d x

\int_{1}^{2} x^{3} d x = \frac{3}{4}

\int_{1}^{2} 6 x d x = 3

= \frac{3}{4} + 3

Simplify

\frac{3}{4} + 3 : \frac{15}{4}

= \frac{15}{4}
