若log(a+3)(2/3)

log a 2/3 log a(2/3) 若log(a+3)(2/3) 等比数列a+log(2)3,a+log(4)3,a+log(8)3求公比q. 若log(根号3)a= -2log(3)7,则a=? 若log(2)3=(1-a)/a则log(3)12RT求详解 若log（3）2=a,用a表示代数式log(2)12=? log(2)3=a,则log(6)4=（ 对数函数题 log a - log b = 3 log (c/2) 求 a = ______________ 证明对数运算法则（1）log(a)(MN)=log(a)(M)+log(a)(N); 　　（2）log(a)(M/N)=log(a)(M)-log(a)(N);（1）log(a)(MN)=log(a)(M)+log(a)(N); 　　（2）log(a)(M/N)=log(a)(M)-log(a)(N); 　　（3）log(a)(M^n)=nlog(a)(M) （n∈R） 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 若log(a)2=m,log(a)3=n,则a^2m+n= 等比数列a+log(2)3,a+log(4)3,a+log(8)3,...的公比为多少? 已知log（14）7=a log(14)5=b 用ab表示log(35)70=log(3)4*log(4)8*log(8)m=log(4)2 求m 若log底数2[log底数3(log底数4)]若log底数2[log底数3(log底数4（x）)]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,则x+y+z= 已知log(2a+3)1/2 已知log(2a+3)1/2 log底数a真数(3分之2)
