Math problem

[div.ide]

What do you mean by equal? Because I'm not sure if you solved it, or just did not read carefully

I mean:

423 134 * 846 267 - 423 133
-----------------------------------------
423 133 * 846 267 - 423 134

Damn i just gave a quick look

you are making me to get a pen and paper -.-"


here we go on a long way

423 133 * 846 267 = 358084340778
358084340778 - 423 133= 358083917645

so now we have 358083917645 / 423 133 * 846 267 - 423 134

Let's do same thing there :
423 133 * 846 267=358083494511
358083494511 - 423 134 = 358083071377

now it's 358083917645 / 358083071377 and this is something i can't make by hand

[div.ide]

WAAAAAAAAAAIT, I misspelled this :/ There should be + sign below fraction

423 134 * 846 267 - 423 133
----------------------------------------- = ?
423 133 * 846 267 + 423 134

Anyway, did you seriously do the multiplication by hand?

[BLOODYALBOZ]

Yes i did i like math, but not rly good at it :-/

and fuck you for your misspell

now it's 1 as i said at first place -.-"

[div.ide]

But there's still easier way to do it
Like, look at numbers:
423 133
423 134
846 267
rings any bell? Anything in common?
Or try that:
1996 * 199719971997 - 1997 * 199619961996 = ?

423 133 * 846 267 + 423 134
----------------------------------------- = 1
423 133 * 846 267 + 423 134


Btw what about 15?
1+5=6
and
(15*4)6+0=6

Not sure what i miss told
Anyway what we are looking
x+y=xn+ yn
Note
if it's 25 for example and it's (25*2)50=5+0 and not 4 + 10

[div.ide]

Oh, I see. I completely missed the point

I think you misread my equation, just like 2pac did
Again:
423 134 * 846 267 - 423 133
----------------------------------------- = ?
423 133 * 846 267 + 423 134

It will be one, but I was hoping someone will be able to show it in a clear way.

[kingW3]

I didn't miss anything,but i guess i should have explained
423 133 *846 267 + 846 267 - 423 133    423 133 * 846 267 + 423 134
-------------------------------------------------- = ---------------------------------------
        423 133 * 846 267 + 423 134            423 133 * 846 267 + 423 134

I just did a few problems for my bro's admission,so wanted to post some here xD
1.If p is a prime number and 3p+1 and 5p+1 are also prime number,how much are there p numbers that satisfy the conditions?
2.Triange ABC on which AB is equal to 6cm and the opposite angle of the side(the ∠ACB angle) is equal to 150°,What is the area of the circumscribed circle on the ABC triangle.
If anyone wants help or explanation of the problem(due of my English ) feel free to ask.

1. from [-1/3 to -1/5]
2. ps the circle is from inside part or outside part ( dat english ) and what you do you mean with area surface ?

What is the area of the circumscribed circle on the ABC triangle. -> outside circle and its area in cm2 (square centimeter)

so if Im right it should be 113.1cm2 (square centimeter)

[div.ide]

I'd guess you're right, T_Bag (fu, posted while I was drawing that shit ).

And, there's exactly one p that satisfies conditions.

[T-Bag]

well, I hope coz diameter of circumscribed circle should be: c/sin γ (gamma) in this case (where c=|AB|), actually it works for any side {a/sin α (alpha) or b/sin β (beta)}.

so its: 6/sin150=12
so area of the circumcircle: πr²

btw regarding 1st question, it cant be:

1. from [-1/3 to -1/5]

as its not prime number 

but just to make sure, did u mean what is "p" or how many "p" (as Im not sure about this since there is no limit so u cant really reach infinity  ) ... just quick one might be p=2.

3*2+1=7
5*2+1=11

2 & 7 & 11 are Prime Numbers

[div.ide]

I guess he meant "how many". Obvioudly 2 satisfies condition, but how would you prove it's the only one? Or that there's more? Or infinity? It's actually quite simple, just think of it.

Anyway, why did you resort to trigonometry? This particular one could be done by perceptive 5th grader understanding how angles work in circle, by noticing one thing.

why not to use trigonometry when its "IMO" good example and the easiest way-became to my mind as first type of solution...btw Im out of school for 8y so I forgot a lot of things

and about 1st question, thats why I asked what did he mean... btw p has to be even number so I cant figure any other then p=2 coz 0 (zero) isnt prime and any other even number isnt prime...so Im waitng for your answer.
