Yes, radicals can't be simplified, so they must be
irrational.

Mia is not correct. The correct answer is:

No, some radicals simplify to rational numbers.

For example, the square root of 4 is 2, which is a rational number. Thus, not all expressions containing radicals necessarily yield an irrational sum.
