Irrational Numbers

# How do you turn an irrational number in to a rational number?

Some Irrational Numbers can be multiplied by another irrational number to yield a rational number - for example the square root of 2 is irrational but if you multiply it by itself, you get 2 - which is rational.

Irrational roots of numbers can yield rational numbers if they are raised to the appropriate power
