What is the square root of 64?

The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, the question is asking for the square root of 64.

The number 64 can be expressed as 8 multiplied by 8 (8 × 8 = 64). Therefore, when we find the square root of 64, we get 8, since 8 is the number that, when squared, returns to 64. This makes 8 the correct answer.

Understanding square roots can be supported by knowing that 8 is also a perfect square since it is the result of squaring a whole number. Recognizing perfect squares up to 10 (like 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100) can help in quickly determining square roots of commonly encountered numbers.
