Question

what type of number will result from the expression √19 - 3/2
A. rational
B. integer
C. irrational
D. whole number

Answer 1

To evaluate the expression \( \sqrt{19} - \frac{3}{2} \), we first note:

- \( \sqrt{19} \) is an irrational number because 19 is not a perfect square.
- \( \frac{3}{2} \) is a rational number.

When we subtract a rational number from an irrational number, the result will still be irrational.

Therefore, \( \sqrt{19} - \frac{3}{2} \) is an irrational number.

The correct answer is **C. irrational**.
