Best ResponseYou've already chosen the best response.0they r not, in the polinomila the exponents must be integers

Best ResponseYou've already chosen the best response.3and the answer's wrong. I can see at least one expression, which, when simplified, becomes a polynomial.

Best ResponseYou've already chosen the best response.1@bahrom7893 what expression can be a polynomial?

Best ResponseYou've already chosen the best response.3Simplify each of them and post what you get.

Best ResponseYou've already chosen the best response.0@kaylala : polynomial is something which has power of an integer, not a fraction Say x^2 is a polynomial , not x^2/3 I hope you got this one.

Best ResponseYou've already chosen the best response.1@bahrom7893 1. cant be simplified 2. 12b^2  5 3. still the same 4. same 5. (square root of 3) xy  4 ??????

Best ResponseYou've already chosen the best response.3well technically x^2/3 is a polynomial, x^(2/3) is not.

Best ResponseYou've already chosen the best response.3So once you have simplified it, which one ends up with positive integer exponents?

Best ResponseYou've already chosen the best response.1@bahrom7893 where did you get x^2/3?

Best ResponseYou've already chosen the best response.3nvm that, it was from an example that thinker was talking about. From your own simplified post. Which of those expressions have positive integer exponents?

Best ResponseYou've already chosen the best response.1so, what's the answer per number item?

Best ResponseYou've already chosen the best response.3I'm not going to give you the answer. You are 90% there. Can you just answer which of the expressions, when simplified end up with positive integer exponents? < that expression will be your answer.

Best ResponseYou've already chosen the best response.1doesnt # 2 have a variable in the denominator? @bahrom7893

Best ResponseYou've already chosen the best response.32. 12b^2  where do you see a variable in the denominator? 5

Best ResponseYou've already chosen the best response.1ohhh..ok so the variable hence is a letter. is # 2 the only polynomial out of all? @bahrom7893

bahrom7893

Best ResponseYou've already chosen the best response.3yes. basically polynomials follow a form a*x^(n) where a can be any number, n has to be a positive integer.
