Question

What is the order of surd square root of 31?

Answer 1

Answer:

A root of a positive real quantity is called a surd if its value cannot be exactly determined. It is a number that can’t be simplified to remove a square root (or cube root etc). For example, each of the quantities √3, ∛7, ∜19, (16)^2/5 etc. is a surd

Answer 2

The order of a surd indicates the index of root to be extracted. In n√a, n is called the order of the surd and a is called the radicand. For example: The order of the surd 5√z is 5.
