计算"3log9 (lg2-1)^2+5log25 (lg0.5-2)^2
计算3∧log9(lg2-1)∧2+5log25∧(lg0.5-2)∧2
2^(log4^12)-3^(log9^27)+5^(log25^1/3)等于多少?
计算 (2lg2+lg3)/(1+lg0.6+lg2)
(log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)=
(1)log4 27乘以log25 8乘以log9 5 (2)(log4 3+log8 3)(log3 2+log9 2
(log4 3+log8 3)(log3 2+log9 2)-log1/2 32^1/3+5^(log25 9)
2^log4底12减3^log9底27加5^log25底1/3的值
[(lg2+lg5-lg1)/(2lg0.5+lg8)]*(lg32-lg2) 分步计算步骤,
lg2+lg50+3^1-log9(2)
lg0.5/lg0.9怎么化为-lg2/2lg3-1,要详细哦,跪求,对数
lg5/lg2*lg0.5/lg25为什么得1/2?
计算[(lg2+2lg3)/(2+lg0.9+lg0.2)]^3-4^6×2^(-13)
