help me

2. rorytsm

A polynomial is a monomial or the sum or difference of monomials. Each monomial is called a term of the poynomial

3. Katieann16

i know .

4. Katieann16

@zordoloom

5. rorytsm

so are you asking for the answer? or why that is the answer marked in the picture?

6. Katieann16

im asking for the correct answer because i got this wrong and i wanna know which i got wrong.

7. zordoloom

I think it's all of them except for D

8. rorytsm

yeah, i think D is the only one that isn't because it has a negative exponent in it

9. skullpatrol

B

A polynomial is a sum of terms. Each term of a polynomial can only contain a number (called coefficient) and zero or more variables raised to a natural number (1, 2, 3, ...). If you have a variable as an exponent, or a variable raised to a negative exponenet, or a fractional exponent, that is not a polynomial.

11. Katieann16

b isnt one?

12. Katieann16

@skullpatrol

13. rorytsm

so A wouldn't be one either according to mathstudent's definition

14. zordoloom

Ya, I don't think is a polynomial either.

15. skullpatrol

B & F are both polynomials @Katieann16

16. rorytsm

actually E wouldn't be one either since it has x^4 in the denominator

17. mathstudent55

A has a variable as an exponent. C has a fractional exponent D & E have variables in the denominator

18. Katieann16

so its just B&F

19. rorytsm

pretty sure mathstudent just nailed it

20. skullpatrol

Correct.

21. mathstudent55

Correct, only B and F

22. Katieann16

thank you all(:

23. skullpatrol

np

To get this question right you have to understand the definition of a monomial.
