Let$$x={4\over{(\sqrt5+1)(\root 4\of5+1)(\root 8\of5+1)(\root {16}\of5+1)}}.$$Find $(x+1)^{48}$. I need it kinda quick :) Thanks!!!!!!!
PLEASE PLEASE PLEASE ANSWER IT FASTTTTT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! IT'S 1:30AM!!!!!!!!!!!!!!!!! I NEED TO FINISH THIS SOON!!!!!!!!!!
Find \((\sqrt[16]5-1)(\sqrt[8]{5}-1)(\sqrt[4]{5}-1)(\sqrt5-1)x\). Then divide and expand. Answer is \(125\).
That is really rude, I have reposted problems up to 5 times, what matters is what you learned, not if it is wrong or right.
+112863 hi learning Guest.
It would be nice if you became a member of this forum.
We like to get to know the people who are truly here to learn.
It will be better for you too. Once you are recognized by us as a serious learner you will get better answers more quickly.
You can even message the answerer of your choice and give them a prod if you want to do so. 
Yes I tried to sign in, it doesn't work for me, I have attempted 3 times and it has never worked
+112863 I am very sorry to hear that. 
So you do not have an account OR you have an account but cannot sign in?
Please explain the exact nature of your problem.
There has been some overhaul of the programming for this site recently and I know there have been some teething problems.
If you could not make an account I think that problem may have been fixed. Please try again and let me know how you get on.
(You can post on this thread) I will let admin know if you still cannot make an account.
In the meantime please attach a name (your username ) to your posts.
It will not be official but it will let us get to know you. We will be able to refer to you with a name, not just as an anonymous guest.
