What is an Irrational Number?
An irrational number is a real number that cannot be expressed as a simple fraction (ratio of two integers). Their decimal expansions go on forever without ever repeating a pattern. If n is a positive integer that is not a perfect square, its square root is always irrational.

Pro Tips
Perfect Squares: If n is 1, 4, 9, 16, 25..., then βn is a rational integer.
Precision: Computers can only approximate irrational numbers; their true value is infinite.
Infinite Set: There are infinitely many irrational numbers between any two real numbers.

Fun Facts
"The first irrational number discovered was β2 by the Pythagoreans, which allegedly caused a crisis in their philosophy."
"Most numbers are actually irrational! They are 'uncountable' compared to rational numbers."
"Ο (Pi) and e (Euler's number) are 'transcendental' irrational numbers."
