荣祝18410819029…… 你好 已知an是首项为1.公比为2的等比数列 求 a1Cn0+a2Cn1+.....+a(n-1)Cnn的值 我认为这位同学打错了题目应该是 求 a1Cn0+a2Cn1+.....+a(n+1)Cnn的值 因为a的下脚标总比Cn后面的数大一(否则an的数目会比Cnx的数目多) 更改后该题可用二项式定理解答 我的解答过程如下 解:由题知an=2的n-1次方 原式=Cn0+2Cn1+.....+2的n次方Cnn =1的n次方Cn0+1的n-1次方*2*Cn1+....+1*2的n-1次方Cn(n-1)+2的n次方Cnn =(1+2)的n次方 =3的n次方 回答完毕

@益古2632：It's reported that many a new house( )at present in the disaster area.
