数学试题2345678>CCBABD91011ACBCDABD11【答案】ABD【解析】：对A：取AB中点N易得：面CNF//面AD'E，故CF//面AD'E，A正确；对B：延长AE，BC交于点H，连接FH交CD'于点M（中线交点），所以2CM=D'M，B正确对C：2AE·CDi=AD²+CE²-AC²-EDi²=1+1-5-EDi²≠0，故 C错误;对D：由AD'⊥BD'，可得：BD'=√3，由勾股易得：D'O⊥面ABCE，计算得：CD'=√3，√33将△AD'B与△CD'B放到同一面，由余弦定理易得：AF+CF≥AC=，故D正确.3图2√612【答案】4√213【答案】614【答案】3四、解答题：本题共5小题，共77分.解答应写出文字说明、证明过程或演算步骤.15.已知复数=1+bi（b∈R，i为虚数单位)，1+i（1）求复数2;（2）若复数z=2z-1是关于x的方程x²+mx+n=0的根，求实数m和n的值.【解析】（1）因为==1+bi(b∈R)，1+i1+i(1+i)(1-i)2是纯虚数，可得1-q=0，解得b=1，所以==1+i1+i2.分（2）法一：因为==2=-1=1+2i是方程x²+mx+n=0（m,n∈R)的根，所以(1+2i)²+a(1+2i)+b=0，即a+b-3+(2a+4)i=0,
