Simplify the Radical Expression (3 square root of 3)/( square root of 18)

$\frac{3 \sqrt{3}}{\sqrt{18}}$

Step 1

Combine $\sqrt{3}$ and $\sqrt{18}$ into a single radical.

$3 \sqrt{\frac{3}{18}}$

Step 2

Cancel the common factor of $3$ and $18$ .

Factor $3$ out of $3$ .

$3 \sqrt{\frac{3 (1)}{18}}$

Cancel the common factors.

Factor $3$ out of $18$ .

$3 \sqrt{\frac{3 \cdot 1}{3 \cdot 6}}$

Cancel the common factor.

$3 \sqrt{\frac{3 \cdot 1}{3 \cdot 6}}$

Rewrite the expression.

$3 \sqrt{\frac{1}{6}}$

Step 3

Rewrite $\sqrt{\frac{1}{6}}$ as $\frac{\sqrt{1}}{\sqrt{6}}$ .

$3 \frac{\sqrt{1}}{\sqrt{6}}$

Step 4

Any root of $1$ is $1$ .

$3 \frac{1}{\sqrt{6}}$

Step 5

Multiply $\frac{1}{\sqrt{6}}$ by $\frac{\sqrt{6}}{\sqrt{6}}$ .

$3 (\frac{1}{\sqrt{6}} \cdot \frac{\sqrt{6}}{\sqrt{6}})$

Step 6

Combine and simplify the denominator.

Multiply $\frac{1}{\sqrt{6}}$ by $\frac{\sqrt{6}}{\sqrt{6}}$ .

$3 \frac{\sqrt{6}}{\sqrt{6} \sqrt{6}}$

Raise $\sqrt{6}$ to the power of $1$ .

$3 \frac{\sqrt{6}}{{\sqrt{6}}^{1} \sqrt{6}}$

Raise $\sqrt{6}$ to the power of $1$ .

$3 \frac{\sqrt{6}}{{\sqrt{6}}^{1} {\sqrt{6}}^{1}}$

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

$3 \frac{\sqrt{6}}{{\sqrt{6}}^{1 + 1}}$

Add $1$ and $1$ .

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

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

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

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

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

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

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

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

Cancel the common factor of $2$ .

Cancel the common factor.

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

Rewrite the expression.

$3 \frac{\sqrt{6}}{6^{1}}$

Evaluate the exponent.

$3 \frac{\sqrt{6}}{6}$

Step 7

Cancel the common factor of $3$ .

Factor $3$ out of $6$ .

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

Cancel the common factor.

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