1. iheartfood

Answer choices, A,B,C,D from top to bottom :) which is a polynomial? :)

2. jim_thompson5910

in order to be a polynomial, all exponents (over the variables) must be positive whole numbers

3. jim_thompson5910

the exponents can't be variables

4. iheartfood

okay, all the exponents are numbers in the answer choices tho

5. jim_thompson5910

no

6. iheartfood

7. jim_thompson5910

yes

8. iheartfood

so C is out then right?

9. jim_thompson5910

also, the square root of variables is not allowed

10. jim_thompson5910

if it were a polynomial

11. iheartfood

okay so answer choice A is out... all thats left is B and D right?

12. jim_thompson5910

and finally, dividing by variables (or variable expressions) isn't allowed in polynomials

13. iheartfood

oaky so B is out?? my answer is D. ?? the last one on the answer choice list?

14. jim_thompson5910

yes
