what whole number is equivalent to $sqrt{64}$? enter the answer in the box.
Answer
Explanation:
Step1: Recall square - root definition
The square root of a number (x), (\sqrt{x}), is a value (y) such that (y\times y=x). We need to find a whole number (y) where (y^2 = 64).
Step2: Find the number
We know that (8\times8 = 64) and ((- 8)\times(-8)=64). But we are looking for a whole number. Whole numbers are non - negative integers. So, (\sqrt{64}=8).
Answer:
8
