Is there an easier way to the do the sum , other than trying different combinations?

Set the problem up like this:

Integer Square

1 1
2 4
3 9
4 16
5 25
6 36
7 49
8 64

And you need to get to 75. Once you set the problem up, it shouldn't take more than 30 secs to solve.

Is this the only method to solve this problem?

I'm guessing so. You have 3 unknowns, and the equation would go

x sqrt + y sqrt + z sqrt = 75

Also, you know for sure the highest number is 8.

They way I got it was:
factor 75 first to get (25 * 3),

That gives 5 as one number.

Then look for two numbers that added to 50...49 and 1, or 7 and 1
