Real Number System
• If is an irrational number such that x is a positive rational number and a (a ≠ 1) is a natural number, then is known as a surd. Here, is radical sign, a is order of the surd and x is radicand.
For example, is a surd of order 3.
• A surd whose order is 2 is called quadratic surd.
• Rules for surds:
If x, y ∈ Q, x, y > 0 and a, b, c ∈ N,…
