Answer:

  a≠0 and b≠0 and c≠0 and d≠0

Step-by-step explanation:

No denominator is allowed to be zero. 'c' and 'd' are in the denominator of the numerator and denominator terms. 'a' and 'b' are in the numerator of the denominator term, so will make that term zero if they are zero. In short, none of a, b, c, or d may be zero.

The fact that the expression simplifies to ...

  2acd^3/b

does not mean that the only restriction is b≠0.
