Evaluate 8/( square root of 10)

$\frac{8}{\sqrt{10}}$

Step 1

Multiply $\frac{8}{\sqrt{10}}$ by $\frac{\sqrt{10}}{\sqrt{10}}$ .

$\frac{8}{\sqrt{10}} \cdot \frac{\sqrt{10}}{\sqrt{10}}$

Step 2

Combine and simplify the denominator.

Multiply $\frac{8}{\sqrt{10}}$ by $\frac{\sqrt{10}}{\sqrt{10}}$ .

$\frac{8 \sqrt{10}}{\sqrt{10} \sqrt{10}}$

Raise $\sqrt{10}$ to the power of $1$ .

$\frac{8 \sqrt{10}}{{\sqrt{10}}^{1} \sqrt{10}}$

Raise $\sqrt{10}$ to the power of $1$ .

$\frac{8 \sqrt{10}}{{\sqrt{10}}^{1} {\sqrt{10}}^{1}}$

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

$\frac{8 \sqrt{10}}{{\sqrt{10}}^{1 + 1}}$

Add $1$ and $1$ .

$\frac{8 \sqrt{10}}{{\sqrt{10}}^{2}}$

Rewrite ${\sqrt{10}}^{2}$ as $10$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{10}$ as $10^{\frac{1}{2}}$ .

$\frac{8 \sqrt{10}}{{(10^{\frac{1}{2}})}^{2}}$

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

$\frac{8 \sqrt{10}}{10^{\frac{1}{2} \cdot 2}}$

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

$\frac{8 \sqrt{10}}{10^{\frac{2}{2}}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{8 \sqrt{10}}{10^{\frac{2}{2}}}$

Rewrite the expression.

$\frac{8 \sqrt{10}}{10^{1}}$

Evaluate the exponent.

$\frac{8 \sqrt{10}}{10}$

Step 3

Cancel the common factor of $8$ and $10$ .

Factor $2$ out of $8 \sqrt{10}$ .

$\frac{2 (4 \sqrt{10})}{10}$

Cancel the common factors.

Factor $2$ out of $10$ .

$\frac{2 (4 \sqrt{10})}{2 (5)}$

Cancel the common factor.

$\frac{2 (4 \sqrt{10})}{2 \cdot 5}$

Rewrite the expression.

$\frac{4 \sqrt{10}}{5}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$\frac{4 \sqrt{10}}{5}$

Decimal Form:

$2.52982212 \dots$
