Think about this:

3x=60

Solve x...

Easy? How about if x doesn't equal 20? Try that.

Hint: It is on a certain youtube video

thats impossible ! x has to be equal to 20 ! proof = 3x=60 so 3*20=60! i hope u might be knowing this from before !

Perhaps x and 60 are angles in degrees. Then x could be 140°, which means that 3x = 420° which is the same as 60° for many purposes (certainly as far as the trig functions are concerned)!

Who dares to question rosala?? .... How about a little "fire," Alan (and reinout)...???

Challenge accepted;

$$3x = 60\\

x = \lim_{n->\infty} \begin{pmatrix}

\frac{27n^3+27n^2-27n+27}{\frac{27}{5}n^3+\frac{27}{4}n^2+\frac{27}{3}n+\frac{27}{2}} \\

27^{\frac{1}{n}}+((\frac{1}{n})!)

\end{pmatrix}

\sqrt{((cos(\frac{1}{4}\pi)+isin(\frac{1}{4} \pi))(cos(\frac{1}{4}\pi)-isin(\frac{1}{4} \pi))-e^{i\pi}-2(cos(\frac{3}{4}\pi)+isin(\frac{3}{4} \pi))^4)}\\

\mbox{ where }\begin{pmatrix}

m \\

r

\end{pmatrix} \mbox{ is the combination of m taken r}$$

Let's suppose that it takes three hours to bake a pie. Then how many could we bake in 60 hrs??

Answer....20 pies......and everyone knows that 20 "pi's" ≈ 62.832

So....there's "x".......(more or less)

I am not going to work through that!

BUT I'll take your word for it.

Thumbs up from me.

Chris, it does not take 3 hours to bake a pie. I cook as much as you do and even I know that!

And besides, why can't you put several in the oven at the same time? The bake time would be in parallel not in series!

by the way CPhill melodys right , it doesnt take 3 hours to bake a cake so how can a pie take 3 hours !but melody phill is just supposing it ! and i liked ur pic CPhill ! thumbs up for it ! and i would like to give thumbs up to reinout too for accepting the challenge ! ha ha !

Hmm. I make reinout's expression to be _{5}C_{2}√( 1 - (-1) - 2*(-1) ) = 10*√4 = 10*2 = 20.

20 is 20 however heavily disguised!

Haha, I knew you'd see through it within a second Alan.

'thumbs up' for actually solving it.

i dont understand one thing u people are continuously repeating ! if we can get the proof or the answer then why r we using such hard and unseen methods to show " yeah , heres the proof " or the answer ! or is this the thing that u just dont wanna agree on someone else !
