Determining the square root of a number can sometimes be 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 discover 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 read more is 20.
- Hence, the square root of 400 is 20.
Solve √400 Step by step
To calculate the square root of 400, we need to identify a number that multiplies by another identical number to yield 400. , Evidently , the answer is 20 because 20 * 20 = 400.
- Consequently, √400 = 20
