Answer:
-4 and 4
Step-by-step explanation:
The square root of 16 has two possible answers: -4 and 4
This is because 4 x 4 = 16
AND -4 x -4 = 16
Remember that a negative times a negative is equal to a positive.
So, when you are taking the square root of 16, you have to write both the negative and positive possibility.
