y=log 7 x+1
y=log 7 x+1
设log(a)(x+y)=根号三,log(a)x=1,求log(a)y
y=log(4)(1-2x+x^2) =log(2)[(1-x)^2] /log(2)(4) =2[log(2)|1-x
log(2x)+log(3y)-log(2z) 怎么化简? log3(x^2-2x-6)=2 log(3x+6)=1+l
已知x,y,z均大于1,w不等于0,log x w=24,log y w=40,log xyz w=12,求log z
换底公式的使用!为什么 y=log(1/2) X = - log(2)X
请画出下列图像:log 1/2 (-x) y=log 1/3 /x/
已知log(1/7)[log(3)(log(2)x)]=0
y=log(x-1)次方 求定义域
y=log(1/3)(-x)的图像怎么画
函数y=根号log(1/2)x的定义域
y=quad('x.*log(1+x)',0,1)这是给log(1+x)求积分么?
