Mathematics

For this case we must simplify the following expression:

$\sqrt {48}$

We can rewrite the 48 as the product of:

16 * 3

Also, 16 we can rewrite it as:

16 = 4 ^ 2

Rewriting the expression we have:

$\sqrt {4 ^ 2 * 3}$

By properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So we have to:

$\sqrt {4 ^ 2 * 3} = 4 \sqrt {3}$

$4 \sqrt {3}$
