I'll do #22, and then you will know what to do with the other three.


For any complex number *[z = x + yi], the absolute value of <i>z</i> is given by *[tex \Large |z| = sqrt{x^2 + y^2}].  If either the real part or the imaginary part of the complex number is missing, then that part has a value of zero.
