Step 1.1

Raise $x$ to the power of $1$ .

$\int_{0}^{1} x^{1} x^{2} yd d x$

Step 1.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\int_{0}^{1} x^{1 + 2} yd d x$

Step 1.3

Add $1$ and $2$ .

$\int_{0}^{1} x^{3} yd d x$

Step 2

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

$yd \int_{0}^{1} x^{3} d x$

Step 3

By the Power Rule, the integral of $x^{3}$ with respect to $x$ is $\frac{1}{4} x^{4}$ .

$yd \frac{1}{4} x^{4}]_{0}^{1}$
