lg36-lg4= lg36 x lg9= 2lg5÷3lg2= lg根号3= log2 56 - log2 7 (2是
对数函数计算题lg36-lg4=lg36 x lg9=2lg5÷3lg2=lg根号3=log2 56 - log2 7
lg2+lg5=?2log2^8 lg根号100开5次根是多少啊?
(log8 9/log2 3) =(lg9/lg8)/(lg3/lg2) ,这是为什么尼
(lgx)/(lg1/2)=lg(x)/-(lg2)=-(lg(x)/lg(2))=-log2(x)
lg2+lg5-log2(3)乘log3(2)
lg^2 5+lg2*lg5+lg2=?
问:对数lg十以内值lg1=?lg2=?lg3=?lg4=?lg5=?lg6=?lg=?lg8=?lg9=?lg10=1
Lg25/lg2*lg4/lg3*lg9/lg5=?给个详细说明
(lg3(lg2+lg5)/lg2lg5) *[ lg5(lg3+lg9)/lg3lg9]*lg2=(lg3+2lg3)
lg2^2+lg2*lg5+lg5=lg2(lg2+lg5)+lg5
lg5/2+lg4=?
lg2×lg5=?lg2×lg5=lg?求问号..是lg(2+5)吗?
