Question

Jillian said /25 is irrational because it is a square root. Why is she incorrect?

Answer 1

 Jillian is incorrect because this is a square root simplifying to 5, and as mentioned 5 isn't an irrational number.

Answer 2

Hi there,

Jillian made a wrong assumption because even though this is a square root, this is a perfect square root simplifying to 5. And 5 is not an irrational number.

Hope this helps!
