Find the square of 1 2 .

Here we are required to find the square of the given number 1 2 . We know that square of a number is the product of the given number with itself. Square of a number n is written as n 2 and is equal to n × n . Therefore, n 2 = n × n . Now 1 2 2 = 1 2 × 1 2 = 1 4 . Hence square of 1 2 = 1 4 .

Find the square of 1 3 7 .

Here we are required to find the square of the given number 1 3 7 = 10 7 . We know that square of a number is the product of the given number with itself. Square of a number n is written as n 2 and is equal to n × n . Therefore, n 2 = n × n . Now 10 7 2 = 10 7 × 10 7 = 100 49 = 2 2 49 . Hence square of 1 3 7 = 2 2 49 .
