VM4 - Square of any no.

[crazyboy]

Now till now you know the square of the no. having 5 and 0 at their end...
Now some other...
Square of the no just 1 next to them..(having 0 and 5 as last digit) means 26,31,36,41,46....like that

Easy....
The fanda here is ...
Add the square of the previous no + nth odd no.
For eg . 31^2
= (30)^2 + 31st Odd no. (which is 2n-1, where n starts from 1...means 61) so square of 31 is 900 + 61 = 961...
Easy find others....

Tomorrow we will see the squares of the other nos...
till than bbye
