Z(2-3i)=6+4i求|Z|,Z(2-3i)=6+4i求|Z|,Z(2-3i)=6+4i求|Z|,很简单的,看下面Z(2-3i)=6+4i|Z|=(6+4i)/(2-3i)结果|Z|2-3i解Z=
Z(2-3i)=6+4i 求|Z|,
Z(2-3i)=6+4i 求|Z|,
Z(2-3i)=6+4i 求|Z|,
很简单的,看下面
Z(2-3i)=6+4i
|Z|=(6+4i)/(2-3i)
结果|Z|2-3i
解Z=(6+4i)/(2-3i)=(6+4i)(2+3i)/(2-3i)(2+3i)=(12+26i+12i^2)/(4-9i^2)=26i/13=2i
所以所求=2 也就是虚数模长为2
z=(6+4i)/(2-3i)=(6+4i)(2+3i)/13=(12-12+26i)/13=2i
Z(2-3i)=6+4i
|Z|=(6+4i)/(2-3i)
结果|Z|<>2-3i
z(2-3i)=6+4i
z(2-3i)(2+3i)=(6+4i)(2+3i)
z=(12+26i+12*i^2)/(4-9*i^2)
z=2i
所求的是复数的模结果等于2的平方再开方=2
注释i^2=-1
z=6+4i处以2-3i |Z|=|(6+4i)/(2-3i)|=|6+4i|/|2-3i|=2根号13/根号13=2
直接解出z=(6+4i)除以(2-3i)到这就行。。。他要求的是模。。那么久直接求分子的模再除以分母的模就可以直接求出z的模 得出来答案是2
Z=(6+4i)/(2-3i)=(6+4i)(2+3i)/(2-3i)(2+3i)=(12+26i+12i^2)/(4-9i^2)=26i/13=2i
复数
哥们
Z(2-3i)=6+4i
Z=(6+4i)/(2-3i)
|Z|=|(6+4i)/(2-3i)|=|6+4i|/|2-3i|=2根号13/根号13=2
