Evaluate square root of -17* square root of -17

$\sqrt{- 17} \cdot \sqrt{- 17}$

Step 1

Rewrite $- 17$ as $- 1 (17)$ .

$\sqrt{- 1 (17)} \cdot \sqrt{- 17}$

Step 2

Rewrite $\sqrt{- 1 (17)}$ as $\sqrt{- 1} \cdot \sqrt{17}$ .

$\sqrt{- 1} \cdot \sqrt{17} \cdot \sqrt{- 17}$

Step 3

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

$i \cdot \sqrt{17} \cdot \sqrt{- 17}$

Step 4

Rewrite $- 17$ as $- 1 (17)$ .

$i \cdot \sqrt{17} \cdot \sqrt{- 1 (17)}$

Step 5

Rewrite $\sqrt{- 1 (17)}$ as $\sqrt{- 1} \cdot \sqrt{17}$ .

$i \cdot \sqrt{17} \cdot (\sqrt{- 1} \cdot \sqrt{17})$

Step 6

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

$i \cdot \sqrt{17} \cdot (i \cdot \sqrt{17})$

Step 7

Multiply $i \sqrt{17} (i \sqrt{17})$ .

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

$i^{1} i \sqrt{17} \sqrt{17}$

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

$i^{1} i^{1} \sqrt{17} \sqrt{17}$

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

$i^{1 + 1} \sqrt{17} \sqrt{17}$

Add $1$ and $1$ .

$i^{2} \sqrt{17} \sqrt{17}$

Raise $\sqrt{17}$ to the power of $1$ .

$i^{2} ({\sqrt{17}}^{1} \sqrt{17})$

Raise $\sqrt{17}$ to the power of $1$ .

$i^{2} ({\sqrt{17}}^{1} {\sqrt{17}}^{1})$

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

$i^{2} {\sqrt{17}}^{1 + 1}$

Add $1$ and $1$ .

$i^{2} {\sqrt{17}}^{2}$

Step 8

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

$- 1 {\sqrt{17}}^{2}$

Step 9

Rewrite ${\sqrt{17}}^{2}$ as $17$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{17}$ as $17^{\frac{1}{2}}$ .

$- 1 {(17^{\frac{1}{2}})}^{2}$

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

$- 1 \cdot 17^{\frac{1}{2} \cdot 2}$

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

$- 1 \cdot 17^{\frac{2}{2}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$- 1 \cdot 17^{\frac{2}{2}}$

Rewrite the expression.

$- 1 \cdot 17^{1}$

Evaluate the exponent.

$- 1 \cdot 17$

Step 10

Multiply $- 1$ by $17$ .

$- 17$

Evaluate square root of -17* square root of -17
