(log5/log2+log0.2/log0.5)(log2/log0.2+log0.5/log5) 怎麼算 计算机等於-4
(log5/log2+log0.2/log0.5)(log2/log0.2+log0.5/log5) 怎麼算 计算机等於-4
首先,有这么一个规律
lg0.2=lg5^(-1)=-lg5
对数的底数也满足这个规律
所以呢
log0.2/log0.5=log5/log2
log2/log0.2=-log2/log5
log0.5/log5=-log2/log5
(log5/log2+log0.2/log0.5)(log2/log0.2+log0.5/log5)
=2log5/log2 * (-) 2log2/log5
=-4
(log5/log2+log0.2/log0.5)(log2/log0.2+log0.5/log5) 怎麼算 计算机等於-4
怎样计算(log2)^2+(log5)^2+(2*log2)*log5
(log5)^2+(log2)(log50)=?
(log5)^2+log2·log50
(log2)^2+(log5)^2+log2*log25
对数 log5(35)+2log0.5( 根号2)-log5(0.02)-log5(14)
log2^5乘以log5^2等于多少?
(log3^4+log5^2)(log2^9+log2^根号3)
(log5(10))^3-(log5(2))^3-3log5(10)*log2(5)
lg(1/4)-lg2(5) 2log5(10)+log5(0.25) 2log2(25)-3log2(64) log2(log2(16) )
log2/log5等于多少
若log2(3-2x)+log0.5(3x-1)
(log5)^2+2lg2-(log2)^2 计算
log2^25*log3^2倍根号2*log5^9=
log2^5*log3^2倍根号2*log5^9=
2^(1/2log2 3)+(1/25)^log5 3=
log3 25×log2 27×log5 2^-3=_____
求(log2 5+log4 0.2)(log5 2+log25 0.5)
