Irrational number between 8 and 9?

An irrational number is a number which cannot be expressed as a fraction made of integers. These numbers generally have infinite decimals with no pattern to them whatsoever.

Thus a number such as square root(72), which is 8.485281..., or square root(80), which is 8.944571..., will do nicely.
