Answer: 4 or [tex]\sqrt{4 * 4}[/tex]
To find the square root of a number, remember that there will be two factors that are the same that will give you the product.
Lets start from 1:
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16
As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.
4 and 4 are the same numbers.
Therefore, [tex]\sqrt{16}[/tex] = 4
It can also be written as [tex]\sqrt{4 * 4}[/tex]
