No. 2 is a rational number. Rational numbers are number that can be expressed as a division of two integers, with the denominator not being zero. 2 can be expressed as 2 divided by 1, so it is rational.

Does an irrational number multiplied by an irrational number equal an irrational number?

The product of two irrational numbers may be rational or irrational. For example, sqrt(2) is irrational, and sqrt(2)*sqrt(2) = 2, a rational number. On the other hand, (2^(1/4)) * (2^(1/4)) = 2^(1/2) = sqrt(2), so here two irrational numbers multiply to give an irrational number.
