Determining the square root of a number can sometimes seem 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 recognize that 20 * 20 = 400. Therefore, the square root of 400 is 20.

• Hence, the square root of 400 is 20.

Determine √400 Step by step

To calculate the square root of 400, we need to identify a number that is the product of itself by itself to result in 400. Clearly , the answer is 20 because 20 * 20 = 400.

• , Thus, √400 = 20

Find the Square Root of 400
