解log(√5-2)(9-4√5)√5-2是底解log(√5-2)(9-4√5)√5-2是底解log(√5-2)(9-4√5)√5-2是底log(√5-2)(9-4√5)=log(√5-2)(√5-2

解log(√5-2) (9-4√5)√5-2是底
解log(√5-2) (9-4√5)
√5-2是底

解log(√5-2) (9-4√5)√5-2是底
log(√5-2) (9-4√5)
=log(√5-2) (√5-2)^2
=2

计算:(1) log(2)(3)*log(3)(4)*log(4)(5)(2)log(2)(7)*log(√7)(8) 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) 求log₂25×log₃2√2×log(5)9的结果, log(2)25×log(3)4×log (5)9等于多少? 化简1,log(√3)3√3 2,2log(5)10+log(5)0.25 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 求等式log(2)3*log(3)4*log(4)5*log(5)6*log(6)7*log(7)m=log(3)9时m的值? 解log(√5-2) (9-4√5)√5-2是底 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 用换底公式求log(2)25乘log(3)4乘log(5)9的值 求值:(log(4)3+log(8)3)×(log(3)2+log(9)2)+log(2)(2^5)¼ [log(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log(根号3)1=? 已知lg2=0.301,lg3=0.477,求(1)log(2)1000,(2)log(5)0.5,(3)log(9)8,(4)log(1/2)1/3 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 log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3) (log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8) 解对数函数的不等式.2log a (√(4-x))-log (√a)2≥2log a (x-1)注:log a x.是log以a为底x的对数. 化简,log(5)35+2log(1/2)√2 - log(5)1/50 - log(5)14注意:括号里的为真数,(√2)这个是 根号2
