Square Root of Perfect Squares
The square root of a perfect square is a number that, when multiplied by itself, equals the original perfect square. For example, if a is a perfect square, then its square root is denoted as √ and √a × √a = a.
Example: Find the square root of 81.
Number 81 is a perfect square because it can be expressed as the product of an integer multiplied by itself: 9 × 9 = 81
The square root of 81 is the number that, when multiplied by itself, equals 81. In this case, the square root of 81 is 9, because 9 × 9 = 81.
Therefore, √81 = 9
In general, if (a2 = b), then √b = a. Perfect squares have whole number square roots.
Square Root
Square root of a number is essentially the value that, when multiplied by itself, yields the original number. This concept is denoted by the radical symbol (√) and is expressed as √n or n1/2, where ‘n’ is a positive number.
