Mathematics
1 answer:
Flauer [41]3 years ago
3 0
Here we're dividing, but what actually happens is that we get the " i " out of the denominator:


104i        104i       3-i        312i + 104      312i + 104
------- = --------- * -------- = --------------- = ----------------
 3+i        3+i          3-i            9+1                  10

Note that 3-i is the "conjugate" of 3+i.
