化简1,log(√3)3√3 2,2log(5)10+log(5)0.25 计算:(1) log(2)(3)*log(3)(4)*log(4)(5)(2)log(2)(7)*log(√7)(8) 1、log下标3 2(log下标4 3+log下标8 3)2、log下标1/3 √27+log下标27 1/3 log(2)5×log(5)81×log(3)4+In√e.还有(log(2)3+log(4)9)(log(3)4+1/2log(3)2) 化简(log[4]3+log[8]3)×(log[3]2+log[9]2)如题 化简:(log^3 2+log^9 2)(log^4 3+log^8 3) 化简log(2)3 * log(3)4 * log(4)7 *log(7)16 求值 log【9(下标)】3+log【 9(下标)】27 log【2】(1/2)- log【1/2】2 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 化简2log`5(10)+log`3(0.25)+log`1/5(125)=(2) log`2(根号2)+log`9(27)+(1/4)^log`4(1/16) 注意 `为下角标 对数计算1.{log(4)(3)+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(2)(3)} X {log(3)(4)+log(9)(2)}3.(lg2)^+1g2X 1g5 +1g50 log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3) 化简(log√x^5-logx^3)/logx^2/3log的底数为10 已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 log(2)9log(3)4等于 log(2)9×log(3)4 4^[log(2)3+log(4)8] 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)
