Step 1.2

Multiply $3$ by $15$ .

$8 \sqrt{45 x \cdot x}$

Step 1.3

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

$8 \sqrt{45 (x^{1} x)}$

Step 1.4

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

$8 \sqrt{45 (x^{1} x^{1})}$

Step 1.5

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

$8 \sqrt{45 x^{1 + 1}}$

Step 1.6

Add $1$ and $1$ .

$8 \sqrt{45 x^{2}}$
