Final answer:
The given expression cannot be determined as a whole number due to the presence of the variable x.
Step-by-step explanation:
The given expression is √20x. To determine if it is a whole number, we need to simplify it. We can start by simplifying the expression under the square root, which is 20x. Since this expression contains a variable, x, we cannot determine the exact value without more information. Therefore, we cannot say for certain if √20x is a whole number.
