Question

what is surds and how to recognize it??

Answer 1

a special no represented in root is called surds if there is root u can confirm it is a surd

Answer 2

if n is a positive integer greater than 1 and 'a' is a positive rational number but not nth power of any rational number then ∧(n)√a or a∧(1/n) is called a surd of nth order. In general we say the positive nth root of a is called a surd or a radical. Here a is called radicand, ∧(n)√ is called radical sign and n is called the degree of radical.
