A square root of 16 is 4 and the only square root of 9 is - 3. True or False

The answer is False. The square root of 9 is equal to 3 not - 3. A square root of 16 is indeed 4 because it is a number that can be divided equally into 16. For example another square root for 16 is 2. 9 can only have 1 square root because no other number divides into it equally and the 1 square root is 3.

False - 3 and 3 because 3*3=9 the same for - 3.

-3*-3=9
