在2和8之间插入3个数,使得这5个数成等比数列,求这3个数.急救
设 5个数的比是 q则这 5 个数是 2 2q 2q² 2q³ 8 既 8=2q³q q=√2 根号2所以5个数是 2,2√2,4,4√2,8
中间的就是正负4<img class="ikqb_img" src="http://f./zhidao/wh%3D600%2C800/sign=b477ba8a5b82b2b7a7ca31c/fdf1feec435.jpg" esrc="http://f.hiphotos.baid...
设这个等比数列的公比为q
则有 2，2q，2q&#178;，2q&#179;，8构成等比数列
即：2q&#179;*q=8，q^4=8/2=4,q&#178;=2，q=根号2所以三个数为2根号2；4；4根号2
a5等于8，同时等于a1乘以q的4次方，
