Here are my answers. Can you check if I got the right answers? Thank you!
(x4)/(x^23x4) = x+1
(x^38)/(x2)=x^2+2x+4
(5x)/(x^225)=x5
(x^24x32)/(x^216)=(x8)/(x4)
first one should be 1/(x+1)
second is good
third: 1/(x+5)
4th is ok
Have you not been taught to place restrictions after your answers for variable denominators?
