Rajraj, seems like your question cannot be answered with Google or Wiki's help... Any clues please? Or else you will get all sorts of imaginative answers :PQuote:

Try to express 81, a square, as sum of squares and try to express a few other squares as sum of squares ! :)Quote:

I am ignoring repeat square numbers (like 3^2 = 1^2 + 2^2 + 2^2) otherwise I think we can express a lot of other numbers as square of other numbers. But I am not able to see any pattern here :oops:
My brain can only see this : :lol:
81 = the number whereby it is the square of sum of its digits? = (1+8)^2? :oops: can't be that simple, right? :lol:

If I run across the book again I will verify ! :)
May be somebody can write a script (program) to verify the assertion! :)
Benny Lava : Good job! You get an A ! :lol:
