Sure.

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)

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 \[\sqrt[3]{2^{4}} = 2^{\frac{4}{3}}\]

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!
