This article will discuss about simple method to find the square of two-digit and three-digit numbers.
Sqaure of any two digit number
In order to find square of any two digit number follow the steps given below
Example 1: 642
Let X= FIRST NUMBER 6
Let Y= SECOND NUMBER 4
Write the equation in form of
X2 2XY Y2
By replacing equation with numbers we will get
62 2*6*4 42
=
36 48 16
- In the third number set 16, the digit 1 will act as carry and it will add to the second number set 48
carry 1
+
36 48 6
=
36 49 6
- In the second number set 49, the digit 4 will act as carry and it will add to first number set 36
4 (carry)
+
36 9 6
=
4096 – Answer
Therefore the sqaure of 64 is 4096.
Example 2: 572
Let X= FIRST NUMBER 5
Let Y= SECOND NUMBER 7
Write the equation in form of
X2 2XY Y2
By replacing equation with numbers we will get
52 2*5*7 72
=
25 70 49
- In the third number set 49, the digit 4 will act as carry and it will add to the second number set 70
carry 4
+
25 70 9
=
25 74 9
- In the second number set 74, the digit 7 will act as carry and it will add to first number set 25
7 (carry)
+
25 4 9
=
3249 – Answer
Therefore the sqaure of 57 is 3249.
Sqaure of any three digit number
The steps for finding the square of any 3 digit number is given below
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.
Example 2: 1272
Let X= 12 (pair first 2 digits)
Let Y= 7 (Last digit)
Write the equation in form of
X2 2XY Y2
By replacing equation with numbers we will get
122 2*12*7 72
=
144 168 49
- In the third number set 49, the digit 4 will act as carry and it will add to the second number set 168
carry 4
+
144 168 9
=
144 172 9
- In the second number set 172, the number 17 will act as carry and it will add to first number set 144
17 (carry)
+
144 2 9
=
16129 – Answer
Therefore the sqaure of 127 is 16129.
