Mia is not correct. The statement "anytime there is a radical in an addition expression, it automatically has an irrational number as the sum" is not true.
The correct response is:
No, some radicals simplify to rational numbers.
For example, the expression \( \sqrt{4} + 1 \) simplifies to \( 2 + 1 = 3 \), which is a rational number. Additionally, not all radicals are irrational; some can be simplified to integers or rational numbers.
