Therefore, if n is a square … WebBesides $\pi$ π a large part of irrational numbers are made up of surds, a special group of numbers that involve roots. Can you try and express $\sqrt{2}$ √ 2, $\sqrt[3]{5}$ 3 √ 5 or $-\sqrt{3}$ − √ 3 as fractions? It's impossible! These are all examples of surds, roots that can not be simplified down to a rational number.
