1|lg2是不是log2 10

1|lg2是不是log2 10 1/log2(10) = lg2 为什么log2(10)=1/lg2 为什么log2 10=1/lg2 lg2 lg10000等与多少 lg2 是不是等于log2 速回 lg(1/4)-lg2(5) 2log5(10)+log5(0.25) 2log2(25)-3log2(64) log2(log2(16) ) (1/log2 10) + (1/log5 10) =lg2 + lg5 为什么log2(10)=a,1/a就等于lg2? 1/6(lg1/2+lg1+lg2+lg4+lg8+……+lg1024)*log2(10)=? 为什么lg(log2 10)与lg(lg2)互为相反数 计算 (lg1/2+lg1+lg2+lg4+lg8+.+lg1024)*log2 10 (1) lg5+lg20+(lg2)^2 (2)2^3+log2^5 计算：（lg2)2+3lg5+lg5(1+lg2)+lg8+log2（5）log5（4) 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 =[1/(log2 3)+lg2 3]²-[1/(log2 3)]²-(log2 3)²=2*(1/log2 3)*log2 3,怎么转的啊 log25+lg2*log50+(log2)^2 log2和lg2一样吗 log2√5/56+log^14-1/2log2^35 （2lg2+lg3)/(2+lg0.36+2lg2) √是根号,5/56全在根号下
