If 2^(x)=3^(y)=6^(-z) prove that (1)/(x)+(1)/(y)+(1)/(z)=0

If 2^(x)=3^(y)=6^(-z) find the value of ((1)/(x)+(1)/(y)+(1)/(z))

If 2^x=3^y=6^(-z) find the value of (1/x+1/y+1/z)

(2-3x)/(x)+(2-3y)/(y)+(2-3z)/(z)=0 then (1)/(x)+(1)/(y)+(1)/(z)=

If 2^x=3^y=6^(-z) prove that 1/x+1/y+1/z=0

If |(x^(n),x^(n+2),x^(n+3)),(y^(n),y^(n+2),y^(n+3)),(z^(n),z^(n+2),z^(n+3))| = (x -y) (y -z) (z -x) ((1)/(x) + (1)/(y) + (1)/(z)) , then n equals

The value of ((x-y)^(3)+(y-z)^(3)+(z-x)^(3))/(9(x-y)(y-z)(z-x)) is equal to (a)0(b)(1)/(9)(c)(1)/(3)(d)1

If [{:(1,1,1),(1,-2,-2),(1,3,1):}][{:(x),(y),(z):}]=[{:(0),(3),(4):}] , then [{:(x),(y),(z):}] is equal to
