please answer me.
please.
answer
this is second time I am asking.


I am giving extra points.​

Answer 1

Pure surd has no rational factor except unity. For example 2√2, 2√5,2√7, 2√12, 3√15, 5√30, 7√50, n√x all are pure surds as these have rational numbers only under radical sign or the whole expression purely belongs to a surd.

Answer 2

Step-by-step explanation:

Pure surd has no rational factor except unity. For example 2√2, 2√5,2√7, 2√12, 3√15, 5√30, 7√50, n√x all are pure surds as these have rational numbers only under radical sign or the whole expression purely belongs to a surd. ... A surd having a rational co-efficient other than unity is called a mixed surd.
