Evaluate ( square root of -448)/( square root of -64)

$\frac{\sqrt{- 448}}{\sqrt{- 64}}$

Step 1

Pull out imaginary unit $i$ .

Rewrite $- 448$ as $- 1 (448)$ .

$\frac{\sqrt{- 1 (448)}}{\sqrt{- 64}}$

Rewrite $\sqrt{- 1 (448)}$ as $\sqrt{- 1} \cdot \sqrt{448}$ .

$\frac{\sqrt{- 1} \cdot \sqrt{448}}{\sqrt{- 64}}$

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

$\frac{i \cdot \sqrt{448}}{\sqrt{- 64}}$

Rewrite $- 64$ as $- 1 (64)$ .

$\frac{i \cdot \sqrt{448}}{\sqrt{- 1 (64)}}$

Rewrite $\sqrt{- 1 (64)}$ as $\sqrt{- 1} \cdot \sqrt{64}$ .

$\frac{i \cdot \sqrt{448}}{\sqrt{- 1} \cdot \sqrt{64}}$

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

$\frac{i \cdot \sqrt{448}}{i \cdot \sqrt{64}}$

Step 2

Cancel the common factor of $i$ .

Cancel the common factor.

$\frac{i \cdot \sqrt{448}}{i \cdot \sqrt{64}}$

Rewrite the expression.

$\frac{\sqrt{448}}{\sqrt{64}}$

Step 3

Combine $\sqrt{448}$ and $\sqrt{64}$ into a single radical.

$\sqrt{\frac{448}{64}}$

Step 4

Divide $448$ by $64$ .

$\sqrt{7}$

Step 5

The result can be shown in multiple forms.

Exact Form:

$\sqrt{7}$

Decimal Form:

$2.64575131 \dots$
