sqrt100

The mathematical expression sqrt100 refers to the square root of the number one hundred. The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, sqrt100 asks for the number that, when multiplied by itself, equals 100. The principal square root of 100 is 10, because 10 multiplied by 10 is 100. Mathematically, this is represented as 10 * 10 = 100. It is also true that -10 multiplied by -10 equals 100, so -10 is also a square root of 100. However, the radical symbol (sqrt) conventionally denotes the principal, or non-negative, square root. Therefore, sqrt100 is understood to be 10. This concept is fundamental in arithmetic and algebra, appearing in calculations involving geometry, such as finding the length of a side of a square given its area, and in various equations. The number 100 is a perfect square because its square root is an integer.
