rewrite the fractions and simplify them. a)(-28u^8)/(16u^4) corresponds to (-28/16)*(u^8/u^4)= (-7/4)*(u^4)= (-7u^4)/4 same idea for the other fractions

wouldn't a) be (-7u^2/4)

4. jim_thompson5910

the exponents in part a) subtract 8-4 = 4 so the answer for part a) should be $\Large -\frac{7}{4}u^4$ which is equivalent to $\Large \frac{-7u^4}{4}$
