 Oct 16 comment Converting $2^{16x} \equiv 2^6\text{ (mod 19)}$ to $16x\equiv 6\text{ (mod 18)}$ Thanks! Why is the 2 a primitive root exactly? Your last line says the conversion is always allowed, so why is this relevant? Jun 3 comment Calculating the shortest possible distance between points @Norbert, I'm learning derivatives Jun 3 comment Calculating the shortest possible distance between points Thanks, +1 but I'll accept Brian's answer since it's what my assignment was about Jun 3 comment Calculating the shortest possible distance between points This is a great answer, +1 but I'll accept Brian's answer since it's what my assignment was about Feb 21 comment Solving the equation $- y^2 - x^2 - xy = 0$ thanks a lot andré Feb 21 comment Solving the equation $- y^2 - x^2 - xy = 0$ it does solve the problem, thanks a lot! +1 :) i did expect a different kind of solution. Is this the only way? Feb 20 comment Solving the equation $- y^2 - x^2 - xy = 0$ only real numbers Feb 17 comment Defining equality validity when an equation with two variables exists Thank you, I would accept it as an answer if it wasn't a comment Feb 17 comment Defining equality validity when an equation with two variables exists quite simple indeed, but $y=3$?
