To determine which of the given numbers is not rational, we need to evaluate each one:
1. **√100** = 10 (which is a rational number).
2. **√900** = 30 (which is a rational number).
3. **√19** (this is not a perfect square, hence it is an irrational number).
4. **√0.49** = 0.7 (which is a rational number).
Therefore, the only number that is not rational among the options is **√19**.
1. **√100** = 10 (which is a rational number).
2. **√900** = 30 (which is a rational number).
3. **√19** (this is not a perfect square, hence it is an irrational number).
4. **√0.49** = 0.7 (which is a rational number).
Therefore, the only number that is not rational among the options is **√19**.
