Hey,
I'm not sure if i'm porting this thread under the right topic, but i just have a quick question about complex numbers.
when you square a complex number (eg. z^2; where z=2+4i) can you just solve this by going z*z???
Thanks,
Function

Perhaps function was thinking of |z| which, for a complex number, is $\displaystyle \sqrt{zz*}$ where z* is the complex conjugate of z. For a real number, x, that would be the same as $\displaystyle \sqrt{x^2}$, but not for a non-real complex number.
