Simplify ( square root of 3x)/( square root of 5y)

$\frac{\sqrt{3 x}}{\sqrt{5 y}}$

Step 1

Multiply $\frac{\sqrt{3 x}}{\sqrt{5 y}}$ by $\frac{\sqrt{5 y}}{\sqrt{5 y}}$ .

$\frac{\sqrt{3 x}}{\sqrt{5 y}} \cdot \frac{\sqrt{5 y}}{\sqrt{5 y}}$

Step 2

Combine and simplify the denominator.

Multiply $\frac{\sqrt{3 x}}{\sqrt{5 y}}$ by $\frac{\sqrt{5 y}}{\sqrt{5 y}}$ .

$\frac{\sqrt{3 x} \sqrt{5 y}}{\sqrt{5 y} \sqrt{5 y}}$

Raise $\sqrt{5 y}$ to the power of $1$ .

$\frac{\sqrt{3 x} \sqrt{5 y}}{{\sqrt{5 y}}^{1} \sqrt{5 y}}$

Raise $\sqrt{5 y}$ to the power of $1$ .

$\frac{\sqrt{3 x} \sqrt{5 y}}{{\sqrt{5 y}}^{1} {\sqrt{5 y}}^{1}}$

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

$\frac{\sqrt{3 x} \sqrt{5 y}}{{\sqrt{5 y}}^{1 + 1}}$

Add $1$ and $1$ .

$\frac{\sqrt{3 x} \sqrt{5 y}}{{\sqrt{5 y}}^{2}}$

Rewrite ${\sqrt{5 y}}^{2}$ as $5 y$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{5 y}$ as ${(5 y)}^{\frac{1}{2}}$ .

$\frac{\sqrt{3 x} \sqrt{5 y}}{{({(5 y)}^{\frac{1}{2}})}^{2}}$

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

$\frac{\sqrt{3 x} \sqrt{5 y}}{{(5 y)}^{\frac{1}{2} \cdot 2}}$

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

$\frac{\sqrt{3 x} \sqrt{5 y}}{{(5 y)}^{\frac{2}{2}}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{\sqrt{3 x} \sqrt{5 y}}{{(5 y)}^{\frac{2}{2}}}$

Rewrite the expression.

$\frac{\sqrt{3 x} \sqrt{5 y}}{{(5 y)}^{1}}$

Simplify.

$\frac{\sqrt{3 x} \sqrt{5 y}}{5 y}$

Step 3

Simplify the numerator.

Combine using the product rule for radicals.

$\frac{\sqrt{3 x (5 y)}}{5 y}$

Multiply $5$ by $3$ .

$\frac{\sqrt{15 x y}}{5 y}$
