Simplify 3/( fourth root of 144)

$\frac{3}{\sqrt[4]{144}}$

Step 1

Simplify the denominator.

Rewrite $144$ as $2^{4} \cdot 9$ .

Factor $16$ out of $144$ .

$\frac{3}{\sqrt[4]{16 (9)}}$

Rewrite $16$ as $2^{4}$ .

$\frac{3}{\sqrt[4]{2^{4} \cdot 9}}$

Pull terms out from under the radical.

$\frac{3}{2 \sqrt[4]{9}}$

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

$\frac{3}{2 \sqrt[4]{3^{2}}}$

Rewrite $\sqrt[4]{3^{2}}$ as $\sqrt{\sqrt{3^{2}}}$ .

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

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

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

Step 2

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

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

Step 3

Combine and simplify the denominator.

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

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

Move $\sqrt{3}$ .

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

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

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

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

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

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

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

Add $1$ and $1$ .

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

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

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

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

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

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

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

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

Cancel the common factor of $2$ .

Cancel the common factor.

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

Rewrite the expression.

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

Evaluate the exponent.

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

Step 4

Cancel the common factor of $3$ .

Cancel the common factor.

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

Rewrite the expression.

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

Step 5

The result can be shown in multiple forms.
