计算(log5^3+log25^3)(log9^5+log27^5)

计算(log5^3+log25^3)(log9^5+log27^5) log25 3 为什么等于log5^3 计算3log9 (lg2-1)^2+5log25 (lg0.5-2)^2还有一题化简:log5 √2*log7 9/log5 1/3*log7 三次的根号4= 已知log5(3)=a,log5(4)=b.求：log25(12) 已知log5(3)=a,log5(4)=b.用a,b表示log25(12) 已知log5 3＝a,lOg5 2＝b,求log25 12的值. log25﹙3﹚=a,log25﹙4﹚=b,求log5﹙72﹚ 已知log5 3=a log5 4=b求证 log25 12=1/2(a=b) (log5根号2*log49 81)/(log25 1/3*log7 4开3次方）=? (log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)= (log5根号2*log49^81)/(log25^(1/3)*log7^立方根4) 计算（2lg5^2+log5^3)/(log5^10+0.5log5^0.36+1/3log5^8) 已知log5为底3的对数＝a,log5为底2的对数＝b,求log25为底12的对数的值 已知log5的3次方=a,log5的4次方=b,使用a,b表示log25的12次方 log5(3)+log5(1/3)=?如何计算 计算[log9(5)+log3(5)]乘[log25(3)+log125(9)] 计算?（log 2^5+log4^125）(log5^4+log25^64) log25﹙3﹚=a,log25﹙4﹚=b,求log5﹙72﹚log1/27(1/7)=a,log1/3(1/5)=b,求log81(175)
