*
1 point
square root 7+8
It could be either, because there is one of each type of number.
Irrational, because one of the addends has a radical.
Rational, because both addends are rational.
It is neither because there is no fraction.

To determine whether the sum \(\sqrt{7} + 8\) is rational or irrational, let's analyze the components:
- \(\sqrt{7}\) is an irrational number.
- \(8\) is a rational number.
According to the properties of numbers, the sum of a rational number and an irrational number is always irrational.
So the correct conclusion is:
**Irrational, because one of the addends has a radical.**
