Answer 2

Answer:

A pure surd is a number that cannot be simplified as a whole number or a fraction. It is typically written as the square root of a non-perfect square number. For example, √3 is a pure surd because it cannot be simplified as a whole number or a fraction, while √4 can be simplified as 2, which is a whole number.
