$\frac{3 \sqrt{18}}{2} + \frac{- 3 {\sqrt{6}}^{1 + 1}}{2}$

Add $1$ and $1$ .

$\frac{3 \sqrt{18}}{2} + \frac{- 3 {\sqrt{6}}^{2}}{2}$

Step 5

Simplify terms.

Combine the numerators over the common denominator.

$\frac{3 \sqrt{18} - 3 {\sqrt{6}}^{2}}{2}$

Simplify each term.

Rewrite $18$ as $3^{2} \cdot 2$ .

Factor $9$ out of $18$ .

$\frac{3 \sqrt{9 (2)} - 3 {\sqrt{6}}^{2}}{2}$

Rewrite $9$ as $3^{2}$ .

$\frac{3 \sqrt{3^{2} \cdot 2} - 3 {\sqrt{6}}^{2}}{2}$

Pull terms out from under the radical.

$\frac{3 (3 \sqrt{2}) - 3 {\sqrt{6}}^{2}}{2}$

Multiply $3$ by $3$ .

$\frac{9 \sqrt{2} - 3 {\sqrt{6}}^{2}}{2}$

Step 6

Simplify the numerator.

Rewrite ${\sqrt{6}}^{2}$ as $6$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{6}$ as $6^{\frac{1}{2}}$ .

$\frac{9 \sqrt{2} - 3 {(6^{\frac{1}{2}})}^{2}}{2}$

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

$\frac{9 \sqrt{2} - 3 \cdot 6^{\frac{1}{2} \cdot 2}}{2}$

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

$\frac{9 \sqrt{2} - 3 \cdot 6^{\frac{2}{2}}}{2}$

Cancel the common factor of $2$ .

Cancel the common factor.
