If `log_x y , log_z x , log_y z` are in G.P. xyz = 64 and `x^3 , y^3 , z^3` are in A.P., then

Given that log_(x)y,log_(z)x,log_(y)z are in GP, xyz=64" and "x^(3),y^(3),z^(3) are in A.P. Which one of the following is correct ? x,y and z are

Given that log_(x)y,log_(z)x,log_(y)z are in GP, xyz=64" and "x^(3),y^(3),z^(3) are in A.P. Which one of the following is correct ? xy,yz and zx are

If log x, log y and log z are in AP, then

. If 1, log_y x, log_z y, -15 log_x z are in AP, then

If 1, log_(y) x, log_(z) y , - 15 log_(x) z are in A.P ., then
