Question

what is surds and poor surds​

Answer 1

Answer:

Surds are numbers left in 'square root form' (or 'cube root form' etc). They are therefore irrational numbers. The reason we leave them as surds is because in decimal form they would go on forever and so this is a very clumsy way of writing them.

A surd in which the whole of the rational number is under the radical sign and makes the radicand, is called pure surd. In other words a surd having no rational factor except unity is called a pure surd or complete surd. For example, each of the surds √7, √10, √x, ∛50, ∛x, ∜6, ∜15, ∜x, 172/3, 595/7, m2/13 is pure surd.
