How does one calulate the square of any number?

In most case you must multiply the number by itself.When the number is irrational ( meaning it cannot be expressed as a fraction,) you may end up with a one that is rational ( can be expressed as a fraction).For example, the 2 squared is 2x2=4square root of 2 is irrational but square root of 2 times itself is 2.Pi is an irrational number but PixPi is Pi2 which is still irrational.Even complex numbers can be squared by multiplying the number by itself.So a+bi is a complex number and (a+bi)2 =(a+bi)(a=bi) where i is the square root of -1.

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.
