Question

HELPPPPPPPPP i have the most trouble with math what’s the answer??

Answer 1

For this case we must simplify the following expression:

$\frac {\sqrt {120}} {\sqrt {30}}$

We know that:$120 = 30 * 4 = 30 * 2 ^ 2$

By definition of power properties we have to:

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

Rewriting the given expression we have:

$\frac {\sqrt {2 ^ 2 * 30}} {\sqrt {30}} =\\\frac {2 \sqrt {30}} {\sqrt {30}} = 2$

Answer:

Option A
