#### Answer

1/(7x); x cannot equal 0

#### Work Step by Step

Recall, if two exponents with the same base (in this case, x) are in the numerator and the denominator of a fraction, we subtract the exponent in the numerator by the exponent in the denominator of the fraction. Thus, we obtain: $4x^{3} / 28x^{4} \\\\ 4 / 28 x \\\\1/7x$ x cannot equal 0, for if x equaled 0, then the denominator of the original fraction would simplify to 0, which is not allowed.
