Title: Mathematics ?
Post by: ecHo~ on October 22, 2012, 09:16:05 pm
Welll, here members will post some maths "a little hard one"
So try to get the answer, once someone answer it correctly, you MUST make another math and post it.
I'am gonna start with easy 1.

Notes: X = *
2C x 4 = :.

i being doing too much bionormal and poly stuff i havent seen his in a while

2c*4=?

8c=?

c=-8

if i havent got this right my a in maths mean nothing

I think its 12, if its not, next person type it correctly . Ty
definatly no that :D

How abouuuuuuut
log(412)16
a= log(4)5
b =log(4)6
I think it will be dicimal but no big deal

first equation is really easy
ehm replica anyone with a calculator can answer that
Log[basex]y
anyway ill just give something easy to you people
x^2-9x+3=0
find x

 y = log x
If y = 10, then what is x?

log (10^10) = 10
guys answer mine xD

This was in my test of last week

D=b^2-4ac
D=(-9)^2-4*3
d=81-12
D=69
-b+_/d
---------
2a

9+_/69
---------
    2

-b-_/d
---------
   2a

9-_/69
---------
   2

Fill these in in your calculator and you have x=.   V x=

9+_/69
---------
    2

9-_/69
---------
   2

enjoy

Ps on iphone

Abc formule pim hahaha. Soon you have to do it without calculator haha

Easy plox

Test was a lot harder though like:

Ps accolades should be 1 for both formulas yet i sck so i place 2 accolades

 {x^2-y^2=5
 {x+y=9

Figure out X and Y
(ps i hope i made up some okay formules since i didn't calculate if they are actually okay)

Question 

Tell me the energie that comes free when splitting 300kg aluminium
Use e=mc^2

m= 300 kg
c (Speed of light)= 3x10^8 m/s

Using the formula e=mc^2

e=(300)(3x10^8)^2
e=(300)(9x10^16)

e=2700x10^16 (Answer)

Exactly. Easy as hell. Dont forget to add Joule add the end. If you want to have another  e=mc^2 question, reply below

 {x^2-y^2=5
 {x+y=9

so easy !!!11!!!!
{x^2-y^2=5
{x+y=9

{(x-y)(x+y)=5
{y=9-x

{[x-(9-x)](x+9-x)=5
{y=9-x

{9*(x-9+x)=5
{y=9-x

{9x-81+9x=5
{y=9-x

{18x=86               {x=86/18
{y=9-x          <=> {y=9-(86/18)

{x=86/18   
{y=162/18       so S={86/18,162/18}

Prove that
1/[lg(x)a * log(x)a^2] + 1/[lg(x)a^2 * lg(x)a^3] + ... + 1/[log(x)a^n-1 * lg(x)a^n] = n-1/[n] * (log(a)x)^2
Solve that,
Took me 5 hours solving this =D

Here is a Math Question That i did in a exam :

Fred is A farmer and he got 10 chicken , if one chicken make 2 eggs per day and fred add 1 new chicken every 2 weeks , how many times does he eat bacon on breakfast ?  ;D
Title: Re: Mathematics ?
Post by: 'PL' on December 27, 2012, 02:15:48 am
10 Chickens
1 Chicken - (+ 2 eggs)
+1 Chicken - (+2 weeks) = 7x2 = 14 days
Breakfast - 1 day
