Irrational, because both factors are irrational.

Answer 1

To determine the type of number that results from the expression \(512 \cdot \sqrt{16}\), we first evaluate the square root and then perform the multiplication.

1. Calculate \( \sqrt{16} \):
\[
\sqrt{16} = 4
\]

2. Now, substitute back into the expression:
\[
512 \cdot \sqrt{16} = 512 \cdot 4
\]

3. Perform the multiplication:
\[
512 \cdot 4 = 2048
\]

Now, let's analyze the result. The number \(2048\) is a whole number, which is rational (since any integer is a rational number).

Thus, the correct response is:

**Rational, because both numbers are rational.**
