A.eqIdaf4c1f5a0053436cbe0fb662547eb459B.eqId016afb7c00b84515b6c95d3c8de26686C.eqId1662454d4aa84bb48aa0983fac421596D.eqId3332b3b098ff498d9868c4c7e0324c56
已知eqIdcf03f415c7f54b458f18c2a39724e166,则复数eqId0b4fc8a120af4fab80df6ffdcf7c46f8(   )
A.eqIdeb20348f30af4d9fa053384fd55d79f7B.eqId86e93eaaaf8b4127ac6370416016ce3aC.eqId89651754a781498f9acf96e92df09af0D.eqId15e2d047ff514adfaae0fa0fde9ee9ff
任何一个复数eqId957585d272654db38e74143411ba4b17(其中eqId70a27b6ddf6b478285353abb3b1f3741eqId7c74e12bac9f4576a738a38bd0cbe415eqIdb6e15e51d29a47a7aff44f98b1aafaee为虚数单位)都可以表示成:eqId489dfaff3c054ed1bf4c06a1dbb5916c的形式,通常称之为复数eqIda3a2b23fd5664e23a642106c7713d456的三角形式.法国数学家棣莫弗发现:eqIdcefdf716fe92447dac19771fbf23f1e0,我们称这个结论为棣莫弗定理.根据以上信息,下列说法正确的是(   )
A.eqId3245b1adbc4846d6bcbaf2e197fede18
B.当eqIdd571e6dcce5b43e9ac843846356d1dadeqIdb42bc0ae85294d1f9e6800ac7c568097时,eqId7f2caf78277a47d787cb059855b7b137
C.当eqIdd571e6dcce5b43e9ac843846356d1dadeqIdb42bc0ae85294d1f9e6800ac7c568097时,eqId951591a5d1e7406bbba70e8b710531db
D.当eqIdd571e6dcce5b43e9ac843846356d1dadeqId2cd7d3ac3ce849c295ad6c7918b2a262时,若eqIdf458db68122849abb588feb2e682d9ac为偶数,则复数eqIdf22afbd5e192435f9594f588acbfb180为纯虚数
若复数eqId98af4111105e44088472bef2af2faecfeqIdb6e15e51d29a47a7aff44f98b1aafaee为虚数单位),则复数eqIdc4f6339df5e94be1af1552f2b014e86b______.
