To find the square root of a number without a calculator, you need to find the number that, when multiplied by itself, gives you the number. Like the square root of 36 is 6 * 6. The square root of 25 is 5 * 5. The square root of 81 is 9 * 9. That means that\[\sqrt{9\times9}\]You can take one out, because that's what the square root means, right!
