Hello shashank bhai....is question ke bahut sare answer possible hai.....

Let c= 0, a=9

Then b^2 = a^3 ; b= 27

d = 0

So b-d = 27

Let a = 25 and c=16

b^2 = a^3 ; b= 125

d = 32

So b-d = 93........

Ek or condition hona chahiye to specify the exact answer

The question is actually log[a](b) = 3/2 log[c](d)=5/4;[] sqre brackets is base .Please give a general solution . Quickly . Also in case its hit an' trial with 1 set satisfyin' answer can someone prove no other set will satisfy the eqn.
