integral of x(5x^2+x^{1/2})

\int x (5 x^{2} + x^{\frac{1}{2}}) d x

\frac{5 x ^{4}}{4} + \frac{2}{5} x^{\frac{5}{2}} + C

Solution steps

\int x (5 x^{2} + x^{\frac{1}{2}}) d x

Expand

x (5 x^{2} + x^{\frac{1}{2}}) : 5 x^{3} + x^{\frac{3}{2}}

= \int 5 x^{3} + x^{\frac{3}{2}} 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 5 x^{3} d x + \int x^{\frac{3}{2}} d x

\int 5 x^{3} d x = \frac{5 x ^{4}}{4}

\int x^{\frac{3}{2}} d x = \frac{2}{5} x^{\frac{5}{2}}

= \frac{5 x ^{4}}{4} + \frac{2}{5} x^{\frac{5}{2}}

Add a constant to the solution

= \frac{5 x ^{4}}{4} + \frac{2}{5} x^{\frac{5}{2}} + C

\int x^{2} + 16 d x

\int \frac{e ^{4 x} + 3}{e ^{2 x}} d x

\int \frac{1}{xx + 1} d x

\int u^{\frac{2}{3}} d u

\int cos (x^{2} + y^{2}) d x
