Best ResponseYou've already chosen the best response.3x^(2) doesn't mean x^(1/2) though you can write x^(2) as 1/x^2

Best ResponseYou've already chosen the best response.3and same for the x^(4) this is not x^(1/4)

Best ResponseYou've already chosen the best response.0ohhh okay so do i multiply the exponents?

Best ResponseYou've already chosen the best response.1\[x^{2} x^{4}\] You're just looking to factor out this function?

Best ResponseYou've already chosen the best response.0well for the exponents, it says to put it in A/B

Best ResponseYou've already chosen the best response.1Oh okay, so as @freckles mentioned :)

Best ResponseYou've already chosen the best response.1Recall that \(x^{\#} \iff \dfrac{1}{x^{\#}}\) Therefore we can write our function over 1 to make the exponents of the variables positive :) and i made a typo, my function should have read \(x^{2} + x^{4}\)*

Best ResponseYou've already chosen the best response.0i got that now! so do we multiply the exponents to get 1/x^8?

Best ResponseYou've already chosen the best response.1All we can do now, is factor out the denominator.

Best ResponseYou've already chosen the best response.3\[x^{2}+x^{4}=\frac{1}{x^2}+\frac{1}{x^4}\] you can combine the fractions by finding a common denominator

Best ResponseYou've already chosen the best response.1I made a really big error. My mistake was in putting the function as a whole in the denominator. In order to turn each variable positive, you must treat each variable as a separate function.

Best ResponseYou've already chosen the best response.1From what @freckles wrote, just find the greatest common denominator between \(x^2\) and \(x^4\).

Best ResponseYou've already chosen the best response.0common denominator is x^4?

Best ResponseYou've already chosen the best response.3that is right \[x^{2}+x^{4} \\ \frac{1}{x^2}+\frac{1}{x^4} \\ \frac{1(x^2)}{x^2(x^2)}+\frac{1}{x^4}\] now you have the same denominator combine the fractions

Best ResponseYou've already chosen the best response.0so itll be x^2/x^4 do i reduce?

Best ResponseYou've already chosen the best response.3you will have \[\frac{x^2+1}{x^4}\]

anonymous

Best ResponseYou've already chosen the best response.0wouldnt that equal to x+1/x^2

Best ResponseYou've already chosen the best response.3no just (x^2+1)/x^4 can't be reduced because you don't have all terms with factor x^2

Best ResponseYou've already chosen the best response.0than would A/B be 2/4? cause the question asked put the exponents as A/B

Best ResponseYou've already chosen the best response.3are you saying we are suppose to write in x^(A/B) form?

freckles

Best ResponseYou've already chosen the best response.3\[x^{2}+x^{4}=x^{\frac{2}{1}}+x^{\frac{4}{1}}\] there is both terms written in x^(A/B) form

Best ResponseYou've already chosen the best response.0oh okay thats easier to understand

Best ResponseYou've already chosen the best response.3I don't get your question can you post your whole question

Best ResponseYou've already chosen the best response.0simplofy the rational expression in the form of A/B. x^2+x^4

freckles

Best ResponseYou've already chosen the best response.3oh in the form A/B well we did that \[\frac{x^2+1}{x^4} \\ \text{ we have } A=x^2+1 \text{ and } B=x^4\]
