$\int \frac{2 a}{\sqrt{x}} - \frac{b}{x^{2}} + 3 c \sqrt[3]{x^{2}} d x$

Step 1

Split the single integral into multiple integrals.

$\int \frac{2 a}{\sqrt{x}} d x + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 2

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

$2 a \int \frac{1}{\sqrt{x}} d x + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 3.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x}$ as $x^{\frac{1}{2}}$ .

$2 a \int \frac{1}{x^{\frac{1}{2}}} d x + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 3.2

Move $x^{\frac{1}{2}}$ out of the denominator by raising it to the $- 1$ power.

$2 a \int {(x^{\frac{1}{2}})}^{- 1} d x + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 3.3.1

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$2 a \int x^{\frac{1}{2} \cdot - 1} d x + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 3.3.2

Combine $\frac{1}{2}$ and $- 1$ .

$2 a \int x^{\frac{- 1}{2}} d x + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 3.3.3

Move the negative in front of the fraction.

$2 a \int x^{- \frac{1}{2}} d x + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 4

By the Power Rule, the integral of $x^{- \frac{1}{2}}$ with respect to $x$ is $2 x^{\frac{1}{2}}$ .

$2 a (2 x^{\frac{1}{2}} + C) + \int - \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 5

Since $- 1$ is constant with respect to $x$ , move $- 1$ out of the integral.

$2 a (2 x^{\frac{1}{2}} + C) - \int \frac{b}{x^{2}} d x + \int 3 c \sqrt[3]{x^{2}} d x$

Step 6

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

$2 a (2 x^{\frac{1}{2}} + C) - (b \int \frac{1}{x^{2}} d x) + \int 3 c \sqrt[3]{x^{2}} d x$

Step 9

Since $3 c$ is constant with respect to $x$ , move $3 c$ out of the integral.

$2 a (2 x^{\frac{1}{2}} + C) - b (- x^{- 1} + C) + 3 c \int \sqrt[3]{x^{2}} d x$
