Answer 1

☑️ If a is such a positive rational number which is not the square of rational number then ±√a type of numbers are called pure quadratic surds.

☑️ A number in the form of a±√b is called a mixed quadratic surd, where "a" is rational number (non-zero) and √b is a pure quadratic surd.

☑️ All irrational numbers are not surds. For example root over pi (√π) is irrational number but it is not a quadratic surd.

BASED ON THE DETAILS GIVEN ABOVE, YOU CAN NOW IDENTIFY WITH REASON WHICH ONES ARE SURDS AND WHICH ONES ARE NOT FROM ANY GIVEN LIST.
