Use the property that, for a > 0 and b > 0,
√(ab) = √(a) * √(b)
So √(12), which is √(4*3) = √(4) * √(3) = 2√3
To make sure I'm understand this here are two problems .
A more complicated problem for me.
I was testing the results and this works, but can you guys explain why should I place the 4 out and aware the 9.
I don't need the absolute value for y because is never negative.
I was told by someone much more knowledgeable than myself that you don't need the absolute value for x either, because x must be greater than or equal to zero in the original expression.
