Square cube method

1. SATISH SQUARE
SIMPLE METHODS TO FOLLOW THE SQUARE OF ANY 2 DIGIT
NUMBER IS EXPLAINED.
Step 1:
We all know that,
( a + b )
2
= a
2
+ 2*a*b + b
2

Step 2:
take out the plus sign
( a b )
2
= a
2
2*a*b b
2

Now I explain with the numbers,
Take 2 digit number as 37, ( a = 3, b = 7 )
Now write as
( 3 7 )
2
= 3
2
2*3*7 7
2

=09 42 49
=09 42 49
= 13 6 9
(37)
2
= 1369

Now I explain with the numbers,
Take 2 digit number as 37, ( a = 3, b = 7 )
Now write as
( 3 7 )
