log(x-1)(x^2-8x+7)=1,求x的值log(x-1)(x^2-8x+7)=1,求x的值log(x-1)(x^2-8x+7)=1,求x的值由题意易知,x-1=x的平方-8x+7.故解得x=
log(x-1) (x^2-8x+7)=1,求x的值
log(x-1) (x^2-8x+7)=1,求x的值
log(x-1) (x^2-8x+7)=1,求x的值
由题意易知,x-1=x的平方-8x+7.故解得x=1或8
lg(7*2^x+8)>=log(√10) 2^x,求函数f(x)=log(1/2)x*log(1/2)x/4的最小值
log(x-1) (x^2-8x+7)=1,求x的值
log(X+5)+log(X+2)=1
log(1/8)X
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3)
已知log(8)[log(3)X]=0,那么X^(-1/2)=
log底数7[log底数3(log底数2X)]=0,那么x^1/2的值是
1/log(2)x+1/log(3)x+1/log(4)x=1,x=?
log(8)(2)^x加log(7)(1/根号3次49)=1,求x的值
log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,求每步详...log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,
无穷等比数列log(8)x,log(8^2)x,log(8^3)x……各项之和为1/2,则x=,
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
试解关于x的不等式log(2)x+4log(3)x+12log(8)x+n·2^(n-1)·log(2^n)x
y=[log(2)(x/8)][log(2)(2x)] x在[1/2,4]的值域如题
log 8下标 (X-6)+ log 8小标 (x+6)=2 求X
log(x.8)-3log(8,x)=2 要X
2log(x)(25)-3log(25)(x)=1怎么解X啊.急
