Evaluate square root of 49/12

$\sqrt{\frac{49}{12}}$

Step 1

Rewrite $\sqrt{\frac{49}{12}}$ as $\frac{\sqrt{49}}{\sqrt{12}}$ .

$\frac{\sqrt{49}}{\sqrt{12}}$

Step 2

Simplify the numerator.

Rewrite $49$ as $7^{2}$ .

$\frac{\sqrt{7^{2}}}{\sqrt{12}}$

Pull terms out from under the radical, assuming positive real numbers.

$\frac{7}{\sqrt{12}}$

Step 3

Simplify the denominator.

Rewrite $12$ as $2^{2} \cdot 3$ .

Factor $4$ out of $12$ .

$\frac{7}{\sqrt{4 (3)}}$

Rewrite $4$ as $2^{2}$ .

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

Pull terms out from under the radical.

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

Step 4

Multiply $\frac{7}{2 \sqrt{3}}$ by $\frac{\sqrt{3}}{\sqrt{3}}$ .

$\frac{7}{2 \sqrt{3}} \cdot \frac{\sqrt{3}}{\sqrt{3}}$

Step 5

Combine and simplify the denominator.

Multiply $\frac{7}{2 \sqrt{3}}$ by $\frac{\sqrt{3}}{\sqrt{3}}$ .

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

Move $\sqrt{3}$ .

$\frac{7 \sqrt{3}}{2 (\sqrt{3} \sqrt{3})}$

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

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

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

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

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

$\frac{7 \sqrt{3}}{2 {\sqrt{3}}^{1 + 1}}$

Add $1$ and $1$ .

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

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

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

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

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

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

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

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

Cancel the common factor of $2$ .

Cancel the common factor.

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

Rewrite the expression.

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

Evaluate the exponent.

$\frac{7 \sqrt{3}}{2 \cdot 3}$

Step 6

Multiply $2$ by $3$ .

$\frac{7 \sqrt{3}}{6}$

Step 7

The result can be shown in multiple forms.

Exact Form:

$\frac{7 \sqrt{3}}{6}$

Decimal Form:
