已知log(x+3) (x^2-2-5)=0,求X
已知log(x+3) (x^2-2-5)=0,求X
log(x+3) (x^2-x-5)=0
∵ x+3>0且x+3≠1
x^2-x-5=1
∴(x+2)(x-3)=0
∴x=3
已知log(2){log(3)[log(4)(x)]}=5^0,则x=?
已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3)
已知log(a)x^2>log(a)2x+3,求x的取值范围
已知log(x+3) (x^2-2-5)=0,求X
已知log(8)[log(3)X]=0,那么X^(-1/2)=
已知log(2)X,log(2)|X|,log(2)(-X),-log(2)X的图像怎么画?不过(3) 就是将log(2)X的x换成-x,就是关于轴对称。关于哪个轴对称啊?
已知log(2)x=5,log(3)y=-2,求log(6)[3x/4y]...(括弧者为底数)
log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
log(X+5)+log(X+2)=1
log(2)(x)log(2)(4x)-3log(2)(x)-12=0
(log(2)(x))^3-4(log(4)(x))^2+log(16)(x)=0
已知0<a<1,x=log a 根号2+log a 根号3y=1/2 log a 5z=log a 根号21 -log a 根号3比较x y z 的大小关系x=log a (根号2)+log a (根号3)y=1/2 (log a 5)z=log a (根号21) -log a (根号3)
log(2)(x+4)=3^x
解方程3log(2)(x)+2log(x)(2)-5=0
log以5为底(3x-2)>log以5为底(x+1)
9.已知log(2在log的右下角)x=3,则x^-1/2=( )9.已知log(2在log的右下角)x=3,则x^-1/2=( )
2 log(3x)= log 4 +log(6-x)怎么求...急
