Answer 1

Is the 3 small?

Answer 2

@Blank  The three is small. :)

Answer 3

Yeah, based on the question none of those choices seem valid

Answer 4

here is an example

3*sqrt(12)

is

6 sqrt(3)

and here is why


leave the 3 out of it. The number outside of the sqrt sign and focus on the inside.

usually when you got sqrt(a) the number inside which is a can be expressed as

a=b*b*c in my case 12=2*2*3 the b part which is 2 can be taken to the out side like this

3*(2)*sqrt(3) notice you only left with the c part which is 3
