If z1 = 3+2i, z2= 4-i, z3=1+i, find and simplify the following: a) z1 + z2, b) z2 x z3, c)z2* (complex conugate of z2), d) z2/z3.

(a) For part a, simply add the real terms together and the imaginary terms together. z 1 +z 2 = (3+2i)+(4-i) = 7+i b). (b) For part b, multiply the brackets out, remembering that i 2 =-1. z 2 x z 3 = (4-i)(1...
