设i为虚数单位,则复数(5-6i)╱i等于A.6+5iB.6-5iC.-6+5iD.-6-5i设i为虚数单位,则复数(5-6i)╱i等于A.6+5iB.6-5iC.-6+5iD.-6-5i设i为虚数单

设i为虚数单位,则复数(5-6i)╱i等于A.6+5i B.6-5i C.-6+5i D.-6-5i
设i为虚数单位,则复数(5-6i)╱i等于
A.6+5i B.6-5i C.-6+5i D.-6-5i

设i为虚数单位,则复数(5-6i)╱i等于A.6+5i B.6-5i C.-6+5i D.-6-5i
((5-6i)╱i)(i)=(5-6i)i╱-1=-6-5i
选D

D
=5/i-6
=5i/i^2 - 6
=-5i-6

设i为虚数单位,则复数(5-6i)╱i等于D.-6-5i

D,提示:i*i=-1
