Understanding 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, we’re looking to find the square root of 64. To do this, we need to find a number that, when squared (multiplied by itself), equals 64.
Calculating the Square Root of 64
To calculate the square root of 64, we can use the mathematical operation of finding a number that, when multiplied by itself, equals 64. The formula for this is √64 = x, where x is the number we’re trying to find. By solving for x, we can determine the square root of 64.
The calculation involves finding the number that, when squared, equals 64. This can be expressed as x^2 = 64, where x is the square root of 64. Solving for x, we find that x = √64 = 8, since 8^2 = 64. Therefore, the square root of 64 is 8.
