FTCE General Knowledge Math Practice Test

What is the square root of 25?

1. 2

2. 5

3. 6

4. 10

The correct answer is: 5

The correct answer is 5, as the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, 5 multiplied by 5 equals 25, confirming that 5 is indeed the square root of 25. The other choices do not yield 25 when squared. For instance, 2 squared is 4, 6 squared is 36, and 10 squared is 100. Therefore, those options do not meet the definition of a square root for the number 25.
