I forget how to simplify these things ): Can someone refresh my memory?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Sure.

OpenStudy (anonymous):

Which is equal to \[(\sqrt{7})^{3}\] A.\[7^{\frac{ 1 }{ 6 }}\]B.\[7^{\frac{ 1 }{ 3 }}\]C.\[7^{\frac{ 2 }{ 3 }}\]D.\[7^{\frac{ 3 }{ 2 }}\] I think maybe it's C or D?

OpenStudy (anonymous):

I just don't know where I should put which exponents when making them into a fraction like that.

OpenStudy (anonymous):

root 7 = 7^1/2 so 7^(1/2*3)=7^(3/2)

OpenStudy (anonymous):

Got it ?

OpenStudy (anonymous):

Yes! Thank you!

OpenStudy (anonymous):

Yw! Inform me if u got any questions :P

OpenStudy (anonymous):

And in the equation \[^{6}\sqrt{48^{3}}\]which of those exponents would be the denominator and which would be the numerator?

OpenStudy (anonymous):

Here is an example u can deduce the answer from it \[\sqrt[3]{2^{4}} = 2^{\frac{4}{3}}\]

OpenStudy (anonymous):

Oh wait, I read the question for that one wrong.. ): Let me rephrase it, I'm sorry

OpenStudy (anonymous):

Same equation that I listed above, but my options are as follows: A.\[2\sqrt{6}\]B.\[4\sqrt{3}\]C.\[4\sqrt{6}\]D.\[16\sqrt{3}\]

OpenStudy (anonymous):

its ok ,Just follow the last example ... It will be 48^(3/6)=48^(1/2)=√48=4√3

OpenStudy (anonymous):

Got it ?

OpenStudy (anonymous):

Yes (: Thank you very much!

OpenStudy (anonymous):

Yvw :)
