is 3sqrt2 - 2sqrt3 simplified 0?

0 ⤊

when you have a number outside of a sqrt do you just multiply the two numbers like 3sqrt2=6?

No!
3sqrt2=sqrt18 and
2sqrt3=sqrt12
So, they are not equal. Therefore
3sqrt2 - 2sqrt3 is not zero.

The answer is "No".
As a check do the calculation:-
3 x 1.414 - 2 x 1.732 = 4.242 - 3.464 = 0.778
ie does not simplify to zero.

No.
2sqrt(3) = sqrt (2^2 *3) = sqrt(12) = sqrt(4*3) =sqrt(4)* sqrt(3) =
2sqrt(3).
3sqrt(2) - 2sqt(3) cannot be further simplified.
