Evaluate ( square root of 2)/( square root of 10)

$\frac{\sqrt{2}}{\sqrt{10}}$

Step 1

Combine $\sqrt{2}$ and $\sqrt{10}$ into a single radical.

$\sqrt{\frac{2}{10}}$

Step 2

Cancel the common factor of $2$ and $10$ .

Factor $2$ out of $2$ .

$\sqrt{\frac{2 (1)}{10}}$

Cancel the common factors.

Factor $2$ out of $10$ .

$\sqrt{\frac{2 \cdot 1}{2 \cdot 5}}$

Cancel the common factor.

$\sqrt{\frac{2 \cdot 1}{2 \cdot 5}}$

Rewrite the expression.

$\sqrt{\frac{1}{5}}$

Step 3

Rewrite $\sqrt{\frac{1}{5}}$ as $\frac{\sqrt{1}}{\sqrt{5}}$ .

$\frac{\sqrt{1}}{\sqrt{5}}$

Step 4

Any root of $1$ is $1$ .

$\frac{1}{\sqrt{5}}$

Step 5

Multiply $\frac{1}{\sqrt{5}}$ by $\frac{\sqrt{5}}{\sqrt{5}}$ .

$\frac{1}{\sqrt{5}} \cdot \frac{\sqrt{5}}{\sqrt{5}}$

Step 6

Combine and simplify the denominator.

Multiply $\frac{1}{\sqrt{5}}$ by $\frac{\sqrt{5}}{\sqrt{5}}$ .

$\frac{\sqrt{5}}{\sqrt{5} \sqrt{5}}$

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

$\frac{\sqrt{5}}{{\sqrt{5}}^{1} \sqrt{5}}$

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

$\frac{\sqrt{5}}{{\sqrt{5}}^{1} {\sqrt{5}}^{1}}$

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

$\frac{\sqrt{5}}{{\sqrt{5}}^{1 + 1}}$

Add $1$ and $1$ .

$\frac{\sqrt{5}}{{\sqrt{5}}^{2}}$

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

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

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

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

$\frac{\sqrt{5}}{5^{\frac{1}{2} \cdot 2}}$

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

$\frac{\sqrt{5}}{5^{\frac{2}{2}}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{\sqrt{5}}{5^{\frac{2}{2}}}$

Rewrite the expression.

$\frac{\sqrt{5}}{5^{1}}$

Evaluate the exponent.

$\frac{\sqrt{5}}{5}$

Step 7

The result can be shown in multiple forms.

Exact Form:

$\frac{\sqrt{5}}{5}$

Decimal Form:

$0.44721359 \dots$
