Answer:

Jillian is incorrect because
√(25) is equal to 5, which is a rational number.

Explanation:

A number is called rational number if it can be defined in the form of
(p)/(q), where p and q are integers, q≠0.

I real number is called irrational if it cannot be defined as in the form of
(p)/(q).

The given number is


√(25)

It can be written as


√(25)=√((5)^2)


√(25)=5


√(25) is equal to 5, which is a rational number.

Therefore
√(25) is a rational numbers and Jillian is incorrect.
