[" If "2^(x)=4^(y)=8^(z)" and "xyz=288" then "],[(1)/(2x)+(1)/(4y)+(1)/(8z)=]

If 2^(x) = 4^(y) = 8^(z) and xyz = 288 , the value of 1/(2x) + 1/(4y) + 1/(8z) is

If x=y=2z and xyz=256, then x=? (a) 2 (b) 4 (c) 8 (d) None of these

If (2x-y)^(2)+(3y-z)^(2)=0 then x:y:z is

If x,y,z are real and 4x^(2)+9y^(2)+16z^(2)=2xyz{(6)/(x)+(4)/(y)+(3)/(z)}

If x+y+z =xyz, then sum(2x)/(1-x^(2))=

x^(3)-8y^(3)+64z^(3)+24xyz

x^(3)+8y^(3)+27z^(3)-18xyz

If x+y+z=xyz then show that (2x)/(1-x^(2))+(2y)/(1-y^(2))+(2z)/(1-z^(2))=(8xyz)/((1-x^(2))(1-y^(2))(1-z^(2)))
