利用对数的换底公式化简下列 1.log(a)c×log(c)a 2.log(2)3×log(3)4×log(4)5×lo
利用对数的换底公式化简下列 1.log(a)c×log(c)a 2.log(2)3×log(3)4×log(4)5×lo
利用对数的换底公式化简下列式:(log(4)3+log(8)3)(log(3)2+log(9)2) 答案是5/4 不知道
对数计算1.{log(4)(3)+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(
对数函数题 log a - log b = 3 log (c/2) 求 a = ______________
利用换底公式证明:log(a)b.log(b)c.log(c)a=1
如果log以3为底[log以4为底(log以5为底的a次方)]等于log以4为底[log以3为底(log以5为底的b次方
log(2)(a)=log(3)(b)=log(5)(c)
计算:(log以4为底3的对数+log以8为底3的对数)(log以3为底2的对数+log以9为底2的对数)- log以½
设A^2+B^2=C^2 求证 log以(C+B)为底A的对数+log(C-B)A=2log(C+B)*log(C-B)
(log以5为底根号2的对数×log以49为底81的对数)÷(log以25为底1/3的对数×log以7为底4的3次方根的
有关对数的计算题(log(4)3+log(8)3)(log(3)2+log(9)2)=?
(LOG(3,4)+LOG(3,8))(LOG(2,3)+LOG(2,9))等于几 看的懂吧
