计算:(1-√3i)/(√3+i)^2=
A.1/4+(√3/4)i
B.-1/4-(√3/4)i
C.1/2+(√3/2)i
D..-1/2-(√3/2)i
是(1-√3*i)/[(√3+i)^2]=?

计算:(1-√3i)/(√3+i)^2=A.1/4+(√3/4)iB.-1/4-(√3/4)iC.1/2+(√3/2)iD..-1/2-(√3/2)i是(1-√3*i)/[(√3+i)^2]=?
(√3+i)^2=2+2√3i
(1-√3i)/(2+2√3i)=(1-√3i)(2-2√3i)/(4+12)=(2-6-4√3i)/16=-(1+√3i)/4

式子写的不对吧?
乘方在哪个位置上?
第一个因式是“根号3倍i”,还是“3与i的积的开方”
