Best ResponseYou've already chosen the best response.3Convert them to exponents and then divide. \[\sqrt[n]{a} = a^{1/n}\]

Best ResponseYou've already chosen the best response.3So for example \[\sqrt[4]{x^3}\text{ divided by }\sqrt[3]{x^2} \] would be \[\frac{x^{\frac{3}{4}}}{x^{\frac{2}{3}}}\] or \[x^{\frac{3}{4}\frac{2}{3}}\]

Best ResponseYou've already chosen the best response.3Which would then be \[x^{\frac{1}{12}}=\sqrt[12]{x}\]

Best ResponseYou've already chosen the best response.3Sometimes the test wants you to give you answer in terms of a radical, then you might have to convert it back. If they will accept the exponent version, then that is the way to go.

Best ResponseYou've already chosen the best response.3yes, what is \[\frac{x^{5/12}}{x^{1/6}}\] Just because they want it in radical form as the answer doesn't mean that you can't do all the work in exponent form and then reconvert. \[\frac{x^a}{x^b}=x^{ab}\] This seems easier to me than trying to figure out the radical forms.

Best ResponseYou've already chosen the best response.3Um. No. What is \[\frac{5}{12}\frac{1}{6}\]?

Best ResponseYou've already chosen the best response.3You are forgetting to put them into common denoms. 5\12  1\6 = 5\12 2\12 = 3\12 = 1\4

Best ResponseYou've already chosen the best response.3When you divide same base different exponents you subtract the exponents from one another. \[\frac{aaaaa}{aa}=\frac{a^5}{a^2}\] \[\frac{aaa}{1}\frac{aa}{aa}=aaa = a^3= a^{52}=a^3\]

Best ResponseYou've already chosen the best response.3No, x^2/3 is wrong. Sorry. If you want to do it in radical form you can. \[\frac{\sqrt[12]{x^5}}{\sqrt[6]{x}}\] can also be done realizing that \[\sqrt[5]{a} = \sqrt[10]{a^2}\] so you can do it that way. You need to convert the index 6 to a twelve

Best ResponseYou've already chosen the best response.0index 12√x^5 x index 6√x doesn't it mean, \(\huge \sqrt[12]{x^5} \times\sqrt[6]x\)

Best ResponseYou've already chosen the best response.3It does say to divide the expressions though. \[\frac{\sqrt[12]{x^5}}{\sqrt[6]{x}}\to\frac{\sqrt[12]{x^5}}{\sqrt[12]{x^2}}\to \] \[\sqrt[12]{\frac{x^5}{x^2}}\to\sqrt[12]{x^{52}}\to\sqrt[12]{x^3}\to \sqrt[4]{\sqrt[3]{x^3}}\to\sqrt[4]{x}\]

Best ResponseYou've already chosen the best response.3The main methods you need to know is that 1) \[\sqrt[5]{x} = \sqrt[10]{x^2}\] 2) \[\frac{\sqrt[12]{a}}{\sqrt[12]{b}}=\sqrt[12]{\frac{a}{b}}\] Yes the fourth root of x is the answer in radical form.

Best ResponseYou've already chosen the best response.3The reason why I suggested immediately to use your exponent conversion is that, if this is algII, you probably learned the exponent rules prior to this and can then use them rather than memorize another set of rules for radicals.

Best ResponseYou've already chosen the best response.3for questions like these, you need to be able to write down the 4 or so rules of exponents and the radical methods as well. Good luck and don't give up. exponents give a lot of people confusion.

Best ResponseYou've already chosen the best response.3yes it was. I am working on the fact that it said to divide the two expressions.
