That's not an equation, it's a, well, I'm not sure what to call it. A human program in english? My math knowledge says an equation is impossible, by the way, because with an equation you're trying to find a) the number that was multiplied and b) the number it was multiplied by(Please note that while these numbers are equal, for the purpose of reversing the process they must be seperate, even though knowing one means you know the other). Now, we know c), the number to find the square root of. Let's say, 64. The square root of 64 is 8. But, to figure out the equation, we have to forget that except to check to see if we have the right answer.

So, a)=? b)=? and c)=64. Is there an equation that will give a) and b) just from c)?

This equation must also work with c)=16.

Triangulation says no.

I came here too late and missed all the fun!

To calculate the square root of a number, I believe it has to be done numerically, so you either have to sum an infinite series or use an iterative method that starts with an estimate and gives successively more accurate values with each iteration.
