Answer 2

\(\dfrac{\sqrt[4]{400}}{\sqrt[4]{5}} = \sqrt[4]{\dfrac{400}{5}} = \sqrt[4]{80} = \sqrt[4]{16\cdot5}\)

Can you finish?

Answer 3

so it would be D correct?

Answer 4

Well, if you want to stop in the middle and entirely ignore my last step and the step after that - which I encouraged you to do.

Answer 5

well 16 * 5 = 80 so it would be d?

Answer 6

We had 80 and then we had 16*5. That is a hint as to the direction we should go. Please don't go back the other direction.

Does this look like we are doing anything? 80 = 16*5 = 80

Hint: \(16 = 2^{4}\)

Answer 7

im confused lbvs

Answer 8

So far, you haven't shown any work at all. You MUST demonstrate that you have SOME connection to the work at hand.

\(\sqrt[4]{16\cdot5} = \sqrt[4]{2^{4}\cdot5} = \sqrt[4]{2^{4}}\cdot\sqrt[4]{5}\)

Now, YOU need to finish. One more thing to do.
