$\sqrt{\frac{7 x^{2}}{3 x}}$

Step 3

Reduce the expression $\frac{7 x^{2}}{3 x}$ by cancelling the common factors.

Factor $x$ out of $7 x^{2}$ .

$\sqrt{\frac{x (7 x)}{3 x}}$

Factor $x$ out of $3 x$ .

$\sqrt{\frac{x (7 x)}{x \cdot 3}}$

Cancel the common factor.

$\sqrt{\frac{x (7 x)}{x \cdot 3}}$

Rewrite the expression.

$\sqrt{\frac{7 x}{3}}$

Step 4

Rewrite $\sqrt{\frac{7 x}{3}}$ as $\frac{\sqrt{7 x}}{\sqrt{3}}$ .

$\frac{\sqrt{7 x}}{\sqrt{3}}$

Step 5

Multiply $\frac{\sqrt{7 x}}{\sqrt{3}}$ by $\frac{\sqrt{3}}{\sqrt{3}}$ .

$\frac{\sqrt{7 x}}{\sqrt{3}} \cdot \frac{\sqrt{3}}{\sqrt{3}}$

Step 6

Combine and simplify the denominator.

Multiply $\frac{\sqrt{7 x}}{\sqrt{3}}$ by $\frac{\sqrt{3}}{\sqrt{3}}$ .

$\frac{\sqrt{7 x} \sqrt{3}}{\sqrt{3} \sqrt{3}}$

Raise $\sqrt{3}$ to the power of $1$ .

$\frac{\sqrt{7 x} \sqrt{3}}{{\sqrt{3}}^{1} \sqrt{3}}$

Raise $\sqrt{3}$ to the power of $1$ .

$\frac{\sqrt{7 x} \sqrt{3}}{{\sqrt{3}}^{1} {\sqrt{3}}^{1}}$

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

$\frac{\sqrt{7 x} \sqrt{3}}{{\sqrt{3}}^{1 + 1}}$

Add $1$ and $1$ .

$\frac{\sqrt{7 x} \sqrt{3}}{{\sqrt{3}}^{2}}$

Rewrite ${\sqrt{3}}^{2}$ as $3$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{3}$ as $3^{\frac{1}{2}}$ .

$\frac{\sqrt{7 x} \sqrt{3}}{{(3^{\frac{1}{2}})}^{2}}$

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

$\frac{\sqrt{7 x} \sqrt{3}}{3^{\frac{1}{2} \cdot 2}}$

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

$\frac{\sqrt{7 x} \sqrt{3}}{3^{\frac{2}{2}}}$

Cancel the common factor of $2$ .
