    The real number in question is sqrt(12)?

    sqrt(12) = sqrt(3*4) = 2sqrt(3)

    sqrt(3) is irrational.

    and we know that the product of a rational and irrational (nonzero) is always irrational.

    \[\sqrt{12} = \sqrt{3*4} = 2*\sqrt{3}\]

    is that okay? sqrt(4)=2 so we can "pull" that out.

    If the number does not have a straight forward square root, then it is irrational. Sqrt(2) and sqrt(3) are irrational. On the other hand sqrt(0.09) = 0.3, so that is rational.
