Answer 1

Step-by-step explanation:

I don't know surds then I will not answer you sorry

Answer 2

Answer:

1) and 3) are surds

REASON:

Surds are imperfect squares i.e. they cannot be expressed in the form of a perfect square.

In case of number 2) which is 361, the 361 is the perfect square of 19, therefore it does not have to be expressed as a surd
