## anonymous 5 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. anonymous

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.

Mee too thaks !

7. anonymous

what do u understand ny monomial?

8. anonymous

i think is binomail coefficient

9. anonymous

Binomial

10. anonymous

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

11. anonymous

What do you think luckey?

12. slaaibak

I'd say it's a rational function.

13. anonymous

14. anonymous

its a monomial with degree 8

15. anonymous

option a 100% sure

16. anonymous

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. anonymous

What

19. slaaibak

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

20. anonymous

slaaibak i think it is not monimial

21. anonymous

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

22. slaaibak

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

23. anonymous

is there diferent that think diferent ?

24. slaaibak

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

25. anonymous

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

26. anonymous

ok so the right answer is c

27. slaaibak

Cool, thanx for clarifying.

28. anonymous

I think so...

29. slaaibak

yes, it's c

30. anonymous

m puzzled

31. anonymous

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

32. anonymous

is it really a non-monomial

33. slaaibak

yes
