Given:
- (23)²
- (35)²
- (52)²
- (96)²
To find:
The value of each of the following using the column method
Calculation:
1. (23)²
By column method we have a=2, b=3
a² 2ab b²
4 12 9
+1 +0
=5 =12
(23)² =529
2. (35)²
By column method we have a=3, b=5
a² 2ab b²
6 30 25
+3 +2
=12 =32
(35)² =1225
3. (52)²
By column method we have a=5, b=2
a² 2ab b²
25 20 4
+2 +0
=27 =20
(52)² =2704
4. (96)²
By column method we have a=9, b=6
a² 2ab b²
81 108 36
+11 +3
=92 =111
(96)² =9216
