Answer:
4
Step-by-step explanation:
In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4. The square root of 9 is 3, because 3 x 3 = 9.
The square root of 16 is 4, because 4 x 4 = 16. Therefore, the value of the square root of 16 is 4.
