Answer 1

To evaluate the expression \( \sqrt{19} - 32 \):

1. Calculate \( \sqrt{19} \). The square root of 19 is an irrational number because 19 is not a perfect square.

2. Next, subtract 32 from \( \sqrt{19} \):
\[
\sqrt{19} - 32
\]
Since you are subtracting a rational number (32) from an irrational number (\( \sqrt{19} \)), the result will also be an irrational number.

Thus, the type of number that results from the expression \( \sqrt{19} - 32 \) is **an irrational number**.
