Finding a square root can be really handy! The square root of a number is one that, when multiplied by itself, gives the original number. You can find square roots using a calculator, or estimate it by finding the two closest perfect squares. For example, the square root of 9 is 3, because 3 x 3 = 9. Is there a specific number you’re trying to find the square root of, or maybe you need help with a math problem?
