解答
你画出logx的 函数图你就知道了
当x大于0或小于0就会得到要证明的两组结果 log1=0
推荐
- 设1＜a≤b≤c,证明logaˇb十logbˇc≤logcˇa≤logbˇa十logcˇb十logaˇc
- 已知1
- 由loga,b=1/logb,a推广到loga,b*logb,c*logc,d=loga,d 这是怎么证明出来的?
- 证明log b/loga+logc/logb+loga/logc>=3（a,b,c>1)
- 已知a,b,c均大于1,若loga x=2,logb x=3,logabc x=12,求logc x
- you shouldn't be late to class again 改错
- 化简[(ab+1)(ab-1)-2a^2b^2+1]/ab
- he asked his daughter what she wanted him to dring for her
