@e.mccormick

Answer 5

8? Not 8. Otherwise correct.

Answer 6

but all the options i have have ^8

Answer 7

\(s^4+5s^4-s^2\) so not 8.

Answer 8

or 8s

Answer 9

\[8s^4\]
\[28s^4 \sqrt{s}\]
\[8s^4-s^2\]
\[28s^4\sqrt{s}-\]

Answer 10

those are what i have to choose from

Answer 11

Someone made a mistake there! The 25 part makes it a 6.

Answer 12

If it was 49, then the root would be 7, and +1 would be 8. They made a mistake.

Answer 13

so what would be the closest answer u think?

Answer 14

What you chose. \(s^4+5s^4-s^2=6s^4+s^2\) So if it marks it wrong, complain with that information.

Answer 15

ok i will
