To find the square root of 81, you can follow these steps:
1. Start by realizing that the square root of a number is a value that, when multiplied by itself, gives the original number. In other words, the square root of x is the number y that satisfies the equation y * y = x.
2. In this case, you want to find the square root of 81, so you need to find a number that, when multiplied by itself, equals 81.
3. The number that meets this condition is 9, because 9 * 9 = 81.
Therefore, the square root of 81 is 9.
