if `x =log_a (bc), y= log_b (ca) and z=log_c(ab)` then `1/(x+1)+1/(y+1)+1/(z+1)`

If x ="log"_(a)(bc), y ="log"_(b)(ca) " and "z = "log"_(c)(ab), then which of the following is correct?

If x=1+log_(a) bc, y=1+log_(b) ca, z=1+log_(c) ab , then (xyz)/(xy+yz+zx) is equal to

If x=1+log_(a) bc, y=1+log_(b) ca, z=1+log_(c) ab , then (xyz)/(xy+yz+zx) is equal to

If x=log_(2a)((bcd)/2), y=log_(3b)((acd)/3), z=log_(4c)((abd)/4) and w=log_(5d)((abc)/5) and 1/(x+1)+1/(y+1)+1/(z+1)+1/(w+1) = log_(abcd)N+1, then value of N/40 is

If "log"_(y) x = "log"_(z)y = "log"_(x)z , then

If x=log_(2a) a,y=log_(3a) 2a and z=log_(4a) 3a then prove that xyz+1=2yz

If log_(4)10=x,log_(2)20=y andlog_(5)8=z .prove that 1/(x+1)+1/(y+1)+1/(z+1)=1.

If log_(a)5=x and log_(a)7=y , then log_(a)sqrt(1,4)=

If x=1+(log)_a b c ,\ y=1+(log)_b c a\ a n d\ z=1+(log)_c a b ,\ then prove that x y z=x y+y z+z xdot

If x=log_(a)bc, y=log_(b)ac and z=log_(c)ab then which of the following is equal to unity ?
