Pythagorean theorem a2+b2=c2 solve for 'c ' without using any numerical values for a,b, or c?

a^2 + b^2 = c^2 Correct presentation is important. We use Shift-6 for powers, and it's nice to include spaces to improve readability.

The rule is you can do any valid operation on both sides of an equation and it will still be equal. Take square root.
