Find :

`( 1/x )^( 1/y - 1/y ) + ( 1/z )^( 1/x - 1/x ) + ( 1/y )^( 1/z - 1/z )` is equal to

Find the value of (( x -y )^3 + ( y - z )^3 + ( z - x )^3 )/ (9 ( x - y )( y - z ) ( z - x )) 1 . 0 2 . 1/9 3 . 1/3 4. 1

(1) / (1 + x + y ^ (- 1)) + (1) / (1 + y + z ^ (- 1)) + (1) / (1 + z + x ^ (- 1))

2 ^ (x) = 5 ^ (y) = 10 ^ (- z) * find ((1) / (x) + (1) / (y) + (1) / (z))

If x^(1//3)+ y ^(1//3)+z^(1//3)= 0 " then what is "(x+y+ z)^(3) equal to ?

If tan^(-1) x + tan^(-1)y + tan^(-1)z= pi then x + y + z is equal to
