Evaluate square root of -10* square root of -10

$\sqrt{- 10} \cdot \sqrt{- 10}$

Step 1

Rewrite $- 10$ as $- 1 (10)$ .

$\sqrt{- 1 (10)} \cdot \sqrt{- 10}$

Step 2

Rewrite $\sqrt{- 1 (10)}$ as $\sqrt{- 1} \cdot \sqrt{10}$ .

$\sqrt{- 1} \cdot \sqrt{10} \cdot \sqrt{- 10}$

Step 3

Rewrite $\sqrt{- 1}$ as $i$ .

$i \cdot \sqrt{10} \cdot \sqrt{- 10}$

Step 4

Rewrite $- 10$ as $- 1 (10)$ .

$i \cdot \sqrt{10} \cdot \sqrt{- 1 (10)}$

Step 5

Rewrite $\sqrt{- 1 (10)}$ as $\sqrt{- 1} \cdot \sqrt{10}$ .

$i \cdot \sqrt{10} \cdot (\sqrt{- 1} \cdot \sqrt{10})$

Step 6

Rewrite $\sqrt{- 1}$ as $i$ .

$i \cdot \sqrt{10} \cdot (i \cdot \sqrt{10})$

Step 7

Multiply $i \sqrt{10} (i \sqrt{10})$ .

Raise $i$ to the power of $1$ .

$i^{1} i \sqrt{10} \sqrt{10}$

Raise $i$ to the power of $1$ .

$i^{1} i^{1} \sqrt{10} \sqrt{10}$

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

$i^{1 + 1} \sqrt{10} \sqrt{10}$

Add $1$ and $1$ .

$i^{2} \sqrt{10} \sqrt{10}$

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

$i^{2} ({\sqrt{10}}^{1} \sqrt{10})$

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

$i^{2} ({\sqrt{10}}^{1} {\sqrt{10}}^{1})$

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

$i^{2} {\sqrt{10}}^{1 + 1}$

Add $1$ and $1$ .

$i^{2} {\sqrt{10}}^{2}$

Step 8

Rewrite $i^{2}$ as $- 1$ .

$- 1 {\sqrt{10}}^{2}$

Step 9

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

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

$- 1 {(10^{\frac{1}{2}})}^{2}$

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

$- 1 \cdot 10^{\frac{1}{2} \cdot 2}$

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

$- 1 \cdot 10^{\frac{2}{2}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$- 1 \cdot 10^{\frac{2}{2}}$

Rewrite the expression.

$- 1 \cdot 10^{1}$

Evaluate the exponent.

$- 1 \cdot 10$

Step 10

Multiply $- 1$ by $10$ .

$- 10$
