log8(9)=a,log2(5)=b,则lg2)=?括号内位真数

log8(9)=a,log2(5)=b,则lg(3)=?括号内为真数 已知log8^9=a,log2^5=b,则lg3=? log8(9)=A log2(5)=B 那么lg3=() log8(9)=a,log2(5)=b,则lg2)=?括号内位真数 (log8 9/log2 3)=? 已知log8 9=a ,log2 5=b,则lg3等于什么(用a,b表示) 已知log2^3=a.则log8^3= log8^9= log2 3=a,则log8 √3=_______ log8的9次方/log2的3次方= 已知3^a=5^b=A,若1/a+1/b=2,则A= 已知log8(9)=a,log2(5)=b,则lg3= 已知log2（log8^m)=log8(log2^m),求log2^m的平方 若log2(log8 m)=log8(log2 m),则(log2 m)^2 log8(9)*log2(3) 1.求值:log8^9/log2^3=?2.设lg2-a,lg3=b,求lg根号54.急,本人数学不好 帮个忙 log8 9=a log=b 求lg2 已知1/2log8(a)+log4(b)=5/2,log8(b)+log4(a^2)=7,则ab= LOG2^3=A,LOG2^5=b,则log2^9/5值是多少 7log8^9=a log3^5=b 求lg2 lg3 lg5
