求(log2)^3+(log5)^3+log5×log8的值.(以10为底)

  求(log2)^3+(log5)^3+log5×log8的值. 求(log2)^3+(log5)^3+log5×log8的值.(以10为底) log2(5) ×log5(8)=3步骤 2log5 10+log5 0.25= 2log5 25-3log2 64= log2(log2 16)= 已知lg2=a,lg3=b,求log3 4,log2 12 (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(3))^x-(log5(3))^x>=(log2(3))^(-y)-(log5(3))^(-y) 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 1、计算log5^35+2log1/2^根号2-log5^1/50-log5^14 2、已知log3^7=a,log2^3=b,求log21^28 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 求x的值 log4^x=-2/3 log2^(log5^x)=0log4^x=-2/3 log2^(log5^x)=0 分开的 求log2(1/125)·log3(1/32)·log5(1/3) 已知log2(5)=m ,log5(3)=n,求用m,n表示lg180 lg^32+lg^35+3log2*log5求详细过程,谢谢 2^(1/2log2 3)+(1/25)^log5 3= log3 25×log2 27×log5 2^-3=_____ log2(3)*log3(5)*log5(8)（具体步骤）
