Answer 2

Hey! :)

So here we need to simplify the square root. The easiest way to do this is split the number into it's lowest common factors.

`√(48)\\√(24*2)\\√(12*2*2)\\√(6*2*2*2)\\√(3*2*2*2*2)`

Now we can notice that there are four 2's. This means that we can write this as

`√(3*4^2) \\√(4^2) *√(3)`

And
`√(4^2)` can be simplified into 4

So our answer is
`4√(3)`

*I want to note here that this could be the only answer anyway, because the rest of the answers aren't simplified.
`√(4)=2,and√(16)=4`
