Is it possible to linearize the equality w.x.y.z=c where each one of real variables w,x,y and z is between 0 and 1. Also, c is an input parameter which is actually a real number between 0 and 1?

From the above equality, it is only clear for me that c≤w≤1 c≤x≤1 c≤y≤1 c≤z≤1.

However, I could not find any way to linearize the equation w.x.y.z=c. Any help would be appreciated.

No, you cannot linearize a product of four real variables.
