When you add a rational number to an irrational number, the result is always an irrational number.
For example:
- Let's say you have a rational number, like \( 30 \) (which can be expressed as \( \frac{30}{1} \)), and an irrational number, like \( \sqrt{2} \).
- If you add them together: \[ 30 + \sqrt{2} \] The result \( 30 + \sqrt{2} \) is irrational.
So if you add any rational number to an irrational number, the result will be irrational.
Summary:
- Rational + Irrational = Irrational
Thus, for your question, if you have \( 30 \) (rational) and \( 4 \) (which is also rational) and are adding any irrational number to either one of them, the sum will still remain irrational when involving at least one irrational number.
