log5(35)-2log5(7/3)+log5(7)-log5(1.8)
log5(35)-2log5(7/3)+log5(7)-log5(1.8)
log5(35)-2log5(7/3)+log5(7)-log5(1.8)
答:
换底公式应用等
log5(35)-2log5(7/3)+log5(7)-log5(1.8)
=log5(5)+log5(7)-2log5(7)+2log5(3)+log5(7)-log5(9/5)
=1+log5(9)-log5(9)+log5(5)
=1+1
=2
log5(35除以(7/3的平方)再乘以7再除以1.8) 数值你自己算吧
log5(35)-2log5(7/3)+log5(7)-log5(1.8)
log5【35】-2log5[7/3】+log5【7】-log5【1.8】 化简
对数 log5(35)+2log0.5( 根号2)-log5(0.02)-log5(14)
对数 log5(35)+2log1/2( 根号2)-log5(1/50)-log5(14)log5(35)+2log1/2( 根号2)-log5(1/50)-log5(14)
计算:log5为底35的对数-2log5为底3分之7的对数+log5为底7的对数-log5为底1.8的对数
log5(4),[log5(3)]²,log4(5)比较大小
2log5(10)+log5(0.25)=?急用
log5(35)-log5(50分之1)-log5(14)=
对数函数 2log5(15)-log5(18)+log5(7)
已知log5 (3)=a,log5(4)=b ,用a,b表示log5(24)
计算:2log5 10+log5 0.25+5log5 25 (都是以5为底的.)
log5 2+log5 3+log5 1/6=?
(log5 3)2 为什么>log5 3
[log5(2)*log7(9)]/[log5(3)*log7(4)] [log5(2)*log7(9)]/[log5(3)*log7(4)]
计算(2lg5^2+log5^3)/(log5^10+0.5log5^0.36+1/3log5^8)
1、计算log5^35+2log1/2^根号2-log5^1/50-log5^14 2、已知log3^7=a,log2^3=b,求log21^28
额,求解指数方程log5(2x²-3x+1) -log5(x-1)+log5(125)=6谢啦,log后的5都是底数!
已知log5(3)=a,log5(4)=b,则log5(270)可表示为
