# What is the simplest radical form of -4 sqrt(6) / sqrt(27)?

Jul 23, 2015

$\frac{- 4 \sqrt{2}}{3}$

#### Explanation:

To get the simplest radical form for this expression, you need to check to see if you can simplify some of the terms, more specifically some of the radical terms.

Notice that you can write

$- 4 \frac{\sqrt{6}}{\sqrt{9 \cdot 3}} = \frac{- 4 \sqrt{6}}{3 \sqrt{3}}$

You can simplify $\sqrt{3}$ from both the denominator and the numerator to get

$\frac{- 4 \cdot \sqrt{2 \cdot 3}}{3 \sqrt{3}} = \frac{- 4 \cdot \sqrt{2} \cdot \cancel{\sqrt{3}}}{3 \cancel{\sqrt{3}}} = \textcolor{g r e e n}{\frac{- 4 \sqrt{2}}{3}}$
