If the positive numbers 3,x,5,y are in a G.P., then : `(x,y)=`

If x^a=y^b=c^c , where a,b,c are unequal positive numbers and x,y,z are in GP, then a^3+c^3 is :

If x^(a)=y^(b)=c^(c), where a,b,c are unequal positive numbers and x,y,z are in GP,then a^(3)+c^(3) is :

If x,2y, 3z are in A.P. where the distinct numbers x,y,z are in G.P., then the common ratio of the G.P. is :

If x,y,z are positive real numbers such that y,z,x are in G.P. and x+y+z=xyz then the maximum value of equals (76)/(x^(4)+x^(2)+7) equals

If x,y,z are positive numbers in A.P., then

If x,y,z are positive numbers in A.P., then

The numbers x, 8, y (xney) are in G.P. and the numbers x, y,-8 are in A.P., then show that x = 16, y = 4

If x ,2y ,3z are in A.P., where the distinct numbers x ,y ,z are in G.P, then the common ratio of the G.P. is a. 3 b. 1/3 c. 2 d. 1/2

If x ,2y ,3z are in A.P., where the distinct numbers x ,y ,z are in G.P, then the common ratio of the G.P. is a. 3 b. 1/3 c. 2 d. 1/2

x and y are two positive integers such that 2,x, y are in A.P. and x, y, 9 are in G.P. then show that -x= 4, y= 6.
