Answer 1

Answer:

The Dwandwa Yoga or 'duplex combination' can be used for general purpose squaring. To proceed further we need to know the Dwandwa of certain numbers. D( abcdef ) = 2af + 2be + 2cd and so on.... As we can see above, D of any number is the sum of square of the middle number and two times the product of the other pairs.
