simplify ^4√100 divided by ^4√5. ive read everything I could on how to solve it and I cant figure it out please help. the 4 are superscript and about the randicand

Question

ipwnbunnies · Answer

$$\frac{\sqrt[4]{100}}{\sqrt[4]{5}} $$
=
$$\sqrt[4]{\frac{100}{5}} = \sqrt[4]{20}$$

anonymous · Answer

I have 4 choices if that will help

ipwnbunnies · Answer

Can't you figure it out from that? The fourth root of 20. You can't really break it down anymore.

anonymous · Answer

A. 5 ^4√2
B. 2 ^4√5
C, 2√5
D.^4√80

anonymous · Answer

those are the options it gives me

ipwnbunnies · Answer

Wat. None of these are right. ;-;  Did you write the problem correctly?

anonymous · Answer

yes it is exponent 4√100 divided by exponent 4√5

ipwnbunnies · Answer

There's no way. The fourth root of 20 is the farthest you can go, with rational number. :/

anonymous · Answer

my answer was 16√2 but Idk if I can simplify it more??

ipwnbunnies · Answer

That'd still be incorrect. Idk dude. Broken question. :3

anonymous · Answer

or could it be D because it cant be broken down

ipwnbunnies · Answer

But 100/5 is 20. ._.

anonymous · Answer

can you teach my how to simplify A so that I can try and figure out the answer that way??

ipwnbunnies · Answer

Idk what you mean. .-. I did all the work in my first post.

anonymous · Answer

no I mean if you look at choice A how do you figure that out and find out how you get to that point

johnweldon1993 · Answer

As long as your question looks exactly as @iPwnBunnies has shown on the first post of the thread...then there is no provided answer choice that is correct.

anonymous · Answer

ok I just checked my email and she said that the 100 is a 400

anonymous · Answer

dooh!!!!

anonymous · Answer

yeah sorry she just said it was a typo and she apologized for confusing me lol

neer2890 · Answer

$$4\sqrt{\frac{ 400 }{ 5 }}=4\sqrt{80}$$

neer2890 · Answer

please consider that 4 is exponent here.

anonymous · Answer

hmmm.... B and D have the same value but B is simplified....

ie,  $\large 2\sqrt[4]5=\sqrt[4]{80} $

anonymous · Answer

the answer is D correct?

anonymous · Answer

D has the same VALUE as B.... (verify that on your calculator)
 
B is the simplified answer... if I had to choose, i'd choose B

neer2890 · Answer

yup.. @dpaInc is correct..!

anonymous · Answer

so B is correct can you show me how B is correct i can get to 4^ square of 80 but how do i simplify??

anonymous · Answer

$\large \sqrt[4]{80}=\sqrt[4]{16\cdot 5}=\sqrt[4]{16}\cdot \sqrt[4]{ 5}=2\cdot \sqrt[4]{ 5}  $

anonymous · Answer

how do you get the 2?

anonymous · Answer

$\large \sqrt[4]{16}=2 $  because  2*2*2*2 = 16

anonymous · Answer

oh ok yeah i forgot thank you for helping me
