To determine the type of number that results from multiplying \(-8\sqrt{}\) and \(45\), let's analyze the expression.
-
\(-8\sqrt{}\) needs clarification, but assuming it references \(-8\) multiplied by something with a square root, we should explicitly define what is under the square root. If it is simply \(-8\) and the square root symbol is used incorrectly, let's assume it means just \(-8\).
-
Multiply \(-8\) and \(45\): \[ -8 \times 45 = -360 \]
-
\(-360\) is:
- An integer (as it is a whole number)
- A rational number (since it can be expressed as \(-360/1\))
Since the prompt seems to assume \(-8\sqrt{}\) was meant to represent \(-8\) in some context, we conclude that:
The final answer is: an integer
