To do an arithmetic operation with two complex numbers:

1.Enter the first complex number, z1 (composed of x1 + i y1), by keying in y1 šx1 š. (For z1z2 , key in the base part, z1, first.)

2.Enter the second complex number, z2, by keying in y2 šx2. (For z1z2 , key in the exponent, z2, second.)

3.Select the arithmetic operation:

Result is 9.1545 – i 4.1689.

Evaluate the expression

 

 

z 1 ⎟ (z2 + z3),

where z1 = 23 + i 13, z2 = –2 + i z2 = 4 – i 3

Since the stack can retain only two complex numbers at a time, perform the calculation as
