Finally if f(x) is not a zero divisor then, by part a, it is never equal to zero. Thus 1=f(x) is well deﬂned and is the multiplicative inverse to f(x) in R. 38. Suppose ab is a zero divisor so ab 6= 0 and there exists c 6= 0 such that abc = 0. Since ab 6= 0 then neither a nor b is zero. WebExercise 6. Let ˚: R!Sbe a ring homomorphism. If r2Ris a zero divisor, is ˚(r) a zero divisor in S? If yes, then prove this statement. If no, give an example of a ring homomorphism ˚and a zero divisor r2Rsuch that ˚(r) is not a zero divisor.
