i can do waht i want but thanks 

:D 

U too:)

U only need to post that like once a day though:)

I like pineapples too, 3 

No two integers divided will produce pi, because it is irrational [not capable of being expressed as a ratio of integers]

However.......if we allow the ratio to be composed of irrational numbers themselves, there are infinite possibilites....namely, this one:

[pi]^(n + 1)  / pi^n           where n is some real number

The answer is not 2.

2 mutliplied by itself once is 2x2 = 4     2²

2 mutliplied by itselft twice is 2x2x2 = 8    2³

2 mutliplied by itself three times is 2x2x2x2 = 16    2⁴

2 mutliplied by itself four times is 2x2x2x2x2 = 32    2⁵

x multiplied by itself n times is x⁽ⁿ⁺¹⁾

So, if x is multiplied by itself five time, this is x⁶

So, x⁶  equals 32

or x equals   ⁶√32    

what are functions??

a relationship or expression involving one or more variables.

Have a great friday!

yeah, and the only place where Bob eats 26 chocalate bar and not get diabetes :D

Possible derivation:
d/dx(log(x cos(x)))
Simplify log(x cos(x)) using the identity log(a b) = log(a)+log(b):
  =  d/dx(log(x)+log(cos(x)))
Differentiate the sum term by term:
  =  d/dx(log(x))+d/dx(log(cos(x)))
The derivative of log(x) is 1/x:
  =  d/dx(log(cos(x)))+1/x
Using the chain rule, d/dx(log(cos(x))) = ( dlog(u))/( du) ( du)/( dx), where u = cos(x) and ( d)/( du)(log(u)) = 1/u:
  =  1/x+d/dx(cos(x)) sec(x)
The derivative of cos(x) is -sin(x):
  =  1/x+-sin(x) sec(x)
Simplify the expression:
Answer: | =  1/x-tan(x)

EXTORSHEN, I did work it out. I only ask when I think the answer is wrong and made a mistake. When I checked, both #2 and 9 didn't work. Only later, check the first comment, did I see that #9 might be the right answer. 

EXTORSHEN thanks for recommending the website btw... but I would like to see a real person do or explain the other questions I had.

CPILL thanks :) love how you explain the steps

sqr(x+7) + 5 = x      subtract 5 from both sides

sqrt(x + 7) = x - 5       square both sides

x + 7 =  x^2 - 10x + 25     

x^2 -11x + 18  = 0   factor

(x -9) (x -2)  = 0      and setting each factor to 0, we have that x = 9   or x = 2

Note......9   is OK in the original problem.......2 is extraneous

HOLD ON ........IM NOT DONE CALCULATING HOW MANY F**KS I DONT GIVE

8 1/2 ft and 18 1/3 ft how many square ft will be blue

Simplify the following:
(8+1/2) (18+1/3)

Put 18+1/3 over the common denominator 3. 18+1/3  =  (3×18)/3+1/3:
(8+1/2) (3×18)/3+1/3

3×18  =  54:
(8+1/2) (54/3+1/3)

54/3+1/3  =  (54+1)/3:
(8+1/2) (54+1)/3

54+1 = 55:
(8+1/2)×55/3

Put 8+1/2 over the common denominator 2. 8+1/2  =  (2×8)/2+1/2:
((2×8)/2+1/2 55)/(3)

2×8  =  16:
((16/2+1/2)×55)/(3)

16/2+1/2  =  (16+1)/2:
((16+1)/2×55)/(3)

16+1 = 17:
17/2×55/3

17/2×55/3 = (17×55)/(2×3):
(17×55)/(2×3)

2×3  =  6:
(17×55)/6

Answer: | 935/6    =158 5/6 square feet.

if u are lazy to work it out jst go to cymath.com

Yes!! :)

Personally I think 2 is extraneous when I checked again.... not sure tho >n<

no problem, we're here to help right ;)

d/dx e^x^2  =

(2x)e^(x^2)

The answer is you are stupid enough to not solve it in the calculator in home page.

:D forum buddy :D lol

Thxx <3

Then I lov u 2! (as a forum buddy)

When I do a problem such as 163,696 squared.. it gives me an answer like 2.679638042e10... how can I convert that to an actual number without the e10?

163,696^2=26,796,380,416

im sure you're nice, that sounded sarcastic, its just a stereotype you shouldnt let it get to you head, im brown there's even more stereotyoes against us but i just dont give a s**t, i just keep thinking that im awesome no matter what people say, YOU SHOULD TOO!! :)

Possible derivation:
d/dx(x log(x)-x)
Differentiate the sum term by term and factor out constants:
  =  -(d/dx(x))+d/dx(x log(x))
The derivative of x is 1:
  =  d/dx(x log(x))-1
Use the product rule, d/dx(u v) = v ( du)/( dx)+u ( dv)/( dx), where u = x and v = log(x):
  =  -1+log(x) d/dx(x)+x d/dx(log(x))
Simplify the expression:
  =  -1+log(x) (d/dx(x))+x (d/dx(log(x)))
The derivative of x is 1:
  =  -1+x (d/dx(log(x)))+1 log(x)
The derivative of log(x) is 1/x:
  =  -1+log(x)+1/x x
Simplify the expression:
Answer: | =  log(x)
