Rationalizing denominator of the form 1/(sqrt5)/5

[MiccyNarc]

I can't figure this out.
I need to rationalize
1___

(sqrt5)

5

and this is somehow supposed to equal (sqrt5), but I can't get it to this point.

I know how to rationalize a denominator of the form
1___

(sqrt5)
but not one as demonstrated above. HELP please

 

[Idonno >_<]

1/rad(5)/5 = 1/rad(5) divided by 1/5 = 1/rad(5) * 5 = 5/rad(5)
5rad(5)/rad(5)*rad(5) = 5rad(5)/5 = rad(5)

0.9999 = 1?

 

[jondy]

0.9999 = 1?

*CRASH*

Fool of a took!

[MiccyNarc]

1/rad(5)/5 = 1/rad(5) divided by 1/5 = 1/rad(5) * 5 = 5/rad(5)
5rad(5)/rad(5)*rad(5) = 5rad(5)/5 = rad(5)

Thank you so much *hugs*

I love HL2.net *tear*

with math I always understood what I need to do, never just how I need to do it.

mainly because I use a calculator WAY too much. I can't even add without my calculator.

I can't think without one.

With math, I understand... actually, pretty much next to nothing. For some reason, math has always terrified and confused me D:

What class is this for?

 

[Danimal]

The answer is 7.

that's weak, I run this baby:

it does, everything, for you. graph in 3d, solve for single or multiple variables, factor, expand, find zeros, and it does happy-endings.

 

[Higlac]

yeah but mine was on sale for about $50 so ha

edit: and i can play tetris and space invaders and pong...

lol u can probably play hl on yours

but, hey im just in HS pre-calc

I am excellent with math. Actually on a test I completely forgot how to convert between 2 forms of an equation. I figured it out using trial and error. In math I get what I am doing and therefor can always(ok maybe not always in geometry and proofs) check my answer.

It was on the first 3/7 sections of the chapter. I got a 75% because I messed up on a few things(silly mistakes). Took the full test on all the chapters later that day, got a 96%, with all my mistakes being silly ones aswell. I did the best on my class...and I also don't use notebooks on any of my math tests while the rest of my class does. Actually I don't even take notes..... can't remember the last time I did. idk Math just comes off as such an easy subject. I mean heres an equation...heres what it does. The rest is just knowing WTF numbers are. I also missed 1/2 of this chapter because I was sick.

Haha, wait until you get into real math: partial differential equations, laplace transforms, gradients, del operators. Right now my hardest course is system control. It's applied math, but you have to analyse a system response to certain inputs using laplace transforms into the frequency domain and then doing root locus and eigenvalues, eigenvectors. It's going to explode my brain and I'm not even doing pure math. I don't want to even know what those nutjobs are learning. Topology sounds hard. Someone told me their exam question was to prove mathematically that it is possible to put a shirt on underneath a vest without taking the vest off.

I have mario and bomberman

How about I prove mathmatically that that's the 3rd biggest waste of time.

Thats easy.
The hard part is copying the answer off someone else.

just jking.

Higher level math is just plain stupid. It doesn't make too much intutive sense, you just have to accept it as brute fact. Especially because the proofs don't make a lick of sense either, unless you jack off to math books.
