(1)(4-5i)(5-i)(2)(1-3i)²(1)(4-5i)(5-i)(2)(1-3i)²(1)(4-5i)(5-i)(2)(1-3i)²(1)原式=20-4i-2
(1)(4-5i)(5-i) (2)(1-3i)²
(1)(4-5i)(5-i) (2)(1-3i)²
(1)(4-5i)(5-i) (2)(1-3i)²
(1)原式=20-4i-25i-5
=15-29i
(2)原式=1-9-6i
=-8-6i
复数计算:(1)i+i^2+i^3+.+i^100(2)i^10+i^20+i^30+.+i^80(3)i*i^2*i^3*.*i^100(4)i*i^3*i^5*.*i^99(5)[(1+i)/(1-i)])[(1+i)/(1-i)]^2)[(1+i)/(1-i)]^3.)[(1+i)/(1-i)]^100
计算;(1),(-8-7i)(-3i) (2),(4-3i)(-5-4i) (3),2i/2-i (4),2+(4).2+i/7+4i
计算:(1)5-(3+2i) (2)(-3-4i)+(2+i)-(1-5i) (3)(2-i)-(2+3i)+4i
⑴(5-6i)+(-2-1)-(3+4i)⑵ 3+4i 分之(1-4i)(1+i)+2+4i
求出式子 I1/3-1/2I+I1/4-1/3I+I1/5-1/4I+.+I1/100-1/99I (I I 表示绝对值)
计算5(4+i)²/i(2+i)
如果i²=-1【1】(2i)²=_____ 5i-3i=_____ 5i*3i=_____ 5i/3i=_____【2】(5-3i)(5+3i)=_____ (5-3i)²=_____5/3i=_____ 5i/3+i=_____【3】若(2+3i)a+(4-i)b=10+5i,求a,b的值
(1)i/1+i(2)2/(1+i)^2(3)(3-i)/(3+4i)(4)(3-4i)(1+2i)/2i
(1)(4-5i)(5-i) (2)(1-3i)²
计算(1+2i)+(3-4i)-(5+6i)
1+i/i等于?(1+i)/i=?
(1+i)^7/1-i+(1-i)^7/1+i-(3-4i)(2+2i)^3/4+3i(要过程,麻烦你们帮帮忙!)
for i=1 to30 if int(i/5)=i/5 then s=s+i i=i+6 next i 求s
已知i为虚数单位,则(4+2i)/(1-i)=( ) A.1+3i B.1-3i C.3-i D.3+i
设i是虚数单位,则负数(1-i)²-4+2i/i-2i等于
i(2-i)(1-2i)过程谢谢
i(2-i)(1-2i)
1.Z1=i^4+i^5+i^6+...+i^12,Z2+i^4×i^5×i^6.i^12,则Z1,Z2的关系是( )A;Z1=Z2 B;Z1=-Z2 C;Z1=1+Z2
