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
