$\int (2 \sqrt{x^{3}} + 7 \sqrt[3]{x^{2}}) d x$

Step 1

Remove parentheses.

$\int 2 \sqrt{x^{3}} + 7 \sqrt[3]{x^{2}} d x$

Step 2

Split the single integral into multiple integrals.

$\int 2 \sqrt{x^{3}} d x + \int 7 \sqrt[3]{x^{2}} d x$

Step 3

Since $2$ is constant with respect to $x$ , move $2$ out of the integral.

$2 \int \sqrt{x^{3}} d x + \int 7 \sqrt[3]{x^{2}} d x$

Step 4

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x^{3}}$ as $x^{\frac{3}{2}}$ .

$2 \int x^{\frac{3}{2}} d x + \int 7 \sqrt[3]{x^{2}} d x$

Step 5

By the Power Rule, the integral of $x^{\frac{3}{2}}$ with respect to $x$ is $\frac{2}{5} x^{\frac{5}{2}}$ .

$2 (\frac{2}{5} x^{\frac{5}{2}} + C) + \int 7 \sqrt[3]{x^{2}} d x$

Step 6

Since $7$ is constant with respect to $x$ , move $7$ out of the integral.

$2 (\frac{2}{5} x^{\frac{5}{2}} + C) + 7 \int \sqrt[3]{x^{2}} d x$

Step 7

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{x^{2}}$ as $x^{\frac{2}{3}}$ .

$2 (\frac{2}{5} x^{\frac{5}{2}} + C) + 7 \int x^{\frac{2}{3}} d x$

Step 8

By the Power Rule, the integral of $x^{\frac{2}{3}}$ with respect to $x$ is $\frac{3}{5} x^{\frac{5}{3}}$ .

$2 (\frac{2}{5} x^{\frac{5}{2}} + C) + 7 (\frac{3}{5} x^{\frac{5}{3}} + C)$
