若a=〖log〗_0.2 6,b=〖 log〗_0.3 6,c=〖0.4〗^6,则a,b,c的大小关系是 若a=〖log〗_0.2 6,b=〖 log〗_0.3 6,c=〖0.4〗^6,则a,b,c的大小关系是请说明理由. 1.随机投点法近似计算积分A=∫_0^1▒e^(〖-x〗^2 ) dx 27-1/ 若a>0,b>0,a*b>1,log(1/2)[a]=ln2,则log(a)[b]与log(1/2)[a]的关系是：（）?(A)log(a)b< log(1/2)[a](B)log(a)b= log(1/2)[a](C)log(a)b>log(1/2)[a](D)log(a)b与log(1/2)[a] 无法比较大小我做到一半就做不下去了：a=(1/2)^(ln2)log 计算定积分∫_0^2▒〖x^2〗√a^2-x^2 ,dx(a>0) 2log(b)x=log(a)x+log(c)x求证,c^2=(ac)^[log(a)b] 对数函数题 log a - log b = 3 log (c/2) 求 a = ______________ 1、若lg2=a,lg3=b,则lg√15=?（用a、b表达）2、若log(15)(5)=m,则log(15)(3)=(用m表示)3、log(2)(3)*log(3)(4)*log(4)(5)*log(5)(6)*log(6)(7)*log(7)(8）=?4、设log(3)(2)=log(2)(3^x),x=?这个对数函数我学的很不好,所以希望过 a=log(3)π b=log(7)6 c=log(2)0.8 哪一个大, X=0.8^_0.1 Y=0.8^_0.2 Z=log3^0. 若A=1 2 1与对角矩阵相似,t=_0 3 t0 0 3 log(2)5=a,log(2)7=b用ab表示log(35)28 log(8)a+log(4)b^2=5,log(8)b+log(4)a^2=7,求log(2)ab的值 已知,l o g 2 7等于a,log 2 5等于b.则用a,b表示log8 35=? log(9)(a)=log(15)(b)=log(25)(a+2b),求b比a的值log(9)(a)=log(15)(b)=log(25)(a+2b),其中9,15和25是底数 求连续函数f(x)使满足等式f(x)+2∫_0^x▒〖f(t)〗 dt=e^(-3x) 公式：log(a)(b)*log(b)(a)=? log(2)3=a,则log(6)4=（
