求值:log2∧5×log5∧1/2

求值:log2∧5×log5∧1/2 求值(log2 5+log4 1/5)(log5 2+log25 1/2) lg(1/4)-lg2(5) 2log5(10)+log5(0.25) 2log2(25)-3log2(64) log2(log2(16) ) 1/log5^7+1/log3^7+1/log2^7 ,求值 log2^5乘以log5^2等于多少? (log5(10))^3-(log5(2))^3-3log5(10)*log2(5) 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 Log5^35+2log1/2^√2-log5^1/50-log5^14求值 求值 3^2-log3(2)= log7(log5(log2(32)))=? 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 5-log3 15 怎样计算（log2)^2+(log5)^2+(2*log2)*log5 log2(5)*log5(8)化简 log2(log5 x)=-1 (log5)^2+(log2)(log50)=? (log5)^2+log2·log50 (log2)^2+(log5)^2+log2*log25 高中数学对数计算求值（log2 125+log4 25+log8 5）*（log125 8+log25 4+log5 2）要用简便运算啊. 化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2
