lg2+lg5-log2(3)乘log3(2)
lg2+lg5-log2(3)乘log3(2)
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
求下列各式的值 1)log2 6+log2 3 2)lg5+lg2 3)log5 3+log5 三分之一 4)log3
计算:(lg2)2+3lg5+lg5(1+lg2)+lg8+log2(5)log5(4)
0.01^(-1/2)-log0.5底8+3^(log3底2)+(lg2)^2+lg2*lg5+lg5=?
(lg2)^3+3lg2乘lg5+(lg5)^3
3+lg5+(lg2)^2
lg2^2+lg2*lg5+lg5=lg2(lg2+lg5)+lg5
1/(1+log3 2)+1/(1+log2 3)=lg3/(lg2+lg3)+lg2/(lg2+lg3)=1解释一下这
:(lg5)的2方+lg2乘lg50
lg^2(2)+lg2乘lg5+lg5
求值lg的平方2+lg2乘lg5+lg5
