Simplify 1/( square root of 7y)

$\frac{1}{\sqrt{7 y}}$

Step 1

Multiply $\frac{1}{\sqrt{7 y}}$ by $\frac{\sqrt{7 y}}{\sqrt{7 y}}$ .

$\frac{1}{\sqrt{7 y}} \cdot \frac{\sqrt{7 y}}{\sqrt{7 y}}$

Step 2

Combine and simplify the denominator.

Multiply $\frac{1}{\sqrt{7 y}}$ by $\frac{\sqrt{7 y}}{\sqrt{7 y}}$ .

$\frac{\sqrt{7 y}}{\sqrt{7 y} \sqrt{7 y}}$

Raise $\sqrt{7 y}$ to the power of $1$ .

$\frac{\sqrt{7 y}}{{\sqrt{7 y}}^{1} \sqrt{7 y}}$

Raise $\sqrt{7 y}$ to the power of $1$ .

$\frac{\sqrt{7 y}}{{\sqrt{7 y}}^{1} {\sqrt{7 y}}^{1}}$

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

$\frac{\sqrt{7 y}}{{\sqrt{7 y}}^{1 + 1}}$

Add $1$ and $1$ .

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

Rewrite ${\sqrt{7 y}}^{2}$ as $7 y$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{7 y}$ as ${(7 y)}^{\frac{1}{2}}$ .

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

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

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

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

$\frac{\sqrt{7 y}}{{(7 y)}^{\frac{2}{2}}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{\sqrt{7 y}}{{(7 y)}^{\frac{2}{2}}}$

Rewrite the expression.

$\frac{\sqrt{7 y}}{{(7 y)}^{1}}$

Simplify.

$\frac{\sqrt{7 y}}{7 y}$
