Answer 1

i would but i gtg srry bud

Answer 2

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

Answer 3

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

Answer 4

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 \[\Large \frac{-7u^4}{4}\]
