Determining the square root of a number can sometimes appear tricky, but for certain numbers like 400, it's relatively straightforward. We know that the square root of a number is a value that, when multiplied by itself, equals the original number. In this case, we need to locate a number that, when multiplied by itself, results in 400. By thinking about perfect squares, we understand that 20 * 20 = 400. Therefore, the square root of 400 is 20.

• Therefore, the square root of 400 is 20.
