简化2log (x + 4) – log(2x + 8) + log(x - 2)
对数计算1.{log(4)(3)+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(
用换底公式简化[log(4)3+log(8)3][log(3)2+log(9)2]
log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)
已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x
4^log(4)[x^2]+3^log(9)[6x]=log(2)[16]
2 log(3x)= log 4 +log(6-x)怎么求...急
solve:log(x)+log(2x)=2
log(X+5)+log(X+2)=1
x=log a 2
已知log(2)X,log(2)|X|,log(2)(-X),-log(2)X的图像怎么画?
