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

Question

anonymous · Answer

yes

anonymous · Answer

Sure.

anonymous · Answer

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?

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

Got it ?

anonymous · Answer

Yes! Thank you!

anonymous · Answer

Yw! Inform me if u got any questions :P

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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.$$16\sqrt{3}$$

anonymous · Answer

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