Question

What is this simplified?

Answer 1

2 square root 15, or the second one down

Answer 2

`2 √(15)`

Step-by-step explanation

We want to simplify

`√(60)`

There is a perfect square under the radical sign:

`√(4 * 15)` Split the radical sign for both factors:

`√(4) * √(15)`

Simplify the first factor

`2 √(15)`

The second option is correct.
