## Sariah 4 years ago Tell whether the expression is a monomial. If it is, name the variable(s) and coefficient, and give the degree of the monomial. - \frac{-4x^{10}}{y^2} Choose one answer. a. Monomial; variables x, y; coefficient -4; degree 8 b. Monomial; variables x, y; coefficient -4; degree 10 c. Not a monomial d. Monomial; variables x, y; coefficient -4; degree 2

Are you sure , I think it is not monomial

4. Sariah

slaaibak help me to solv this

5. slaaibak

I'm not very familiar with this, but I'd say C, since any polynomial should have only non-negative powers. A monomial is a special polynomial, hence the non-negative powers should also apply. Therefore, because this contains y^-2, I'd say C.

6. Sariah

Mee too thaks !

7. luckey

what do u understand ny monomial?

8. Sariah

i think is binomail coefficient

9. Sariah

Binomial

10. luckey

monomial is a single term expression without any addition or subtration operation its definitely a monomial expression no doubt

11. Sariah

What do you think luckey?

12. slaaibak

I'd say it's a rational function.

13. Sariah

14. luckey

its a monomial with degree 8

15. luckey

option a 100% sure

16. Sariah

Ok thanks wait i will give you a medal if you are right... ok in somes minutes i will know it...

17. slaaibak

Wait.

18. Sariah

What

19. slaaibak

Lucky, do you know polynomials only have non-negative powers?

20. Sariah

slaaibak i think it is not monimial

21. agdgdgdgwngo

$- \frac{-4x^{10}}{y^2}$

22. slaaibak

A monomial is a product of positive integer powers of a fixed set of variables (possibly) together with a coefficient

23. Sariah

is there diferent that think diferent ?

24. slaaibak

according to that definition, it is certainly not a monomial.

25. agdgdgdgwngo

It's not a monomial, since not all the exponents of the variables in the expression are positive integers.

26. Sariah

ok so the right answer is c

27. slaaibak

Cool, thanx for clarifying.

28. Sariah

I think so...

29. slaaibak

yes, it's c

30. luckey

m puzzled

31. Sariah

Thanks slaaibak and agdgdgdgwngo the answer is right said the teacher...thanks

32. luckey

is it really a non-monomial

33. slaaibak

yes
