Example 1: 1042
Let X= 10 (pair first 2 digits)
Let Y= 4 (last digit)
Write the equation in form of
X2 2XY Y2
By replacing equation with numbers we will get
102 2*10*4 42
=
100 80 16
- In the third number set 16, the digit 1 will act as carry and it will add to the second number set 80
carry 1
+
100 80 6
=
100 81 6
- In the second number set 81, the digit 8 will act as carry and it will add to first number set 100
8 (carry)
+
100 1 6
=
10816 – Answer
Therefore the sqaure of 104 is 10816.
