here it goes:
Two cars leave from the same point at the same time, one traveling

I want to know how big a number 361! is .
To see this, i want to convert 361! to the form of  n*10^m .
n: doesnt have to be integer, m: integer
Could someone help me?

Can somebody help me ?
How can understand  the right order of these numbers
of course  whitout  the help of calculator...only the use the brain !!!

Am compiling an Excel spreadsheet as part of a project based on mortgage
payments. I want a series of sheets demonstrating the pattern of interest
payments/capital balance remaining, effect of overpayment etc.
I am using the following formula to calculate monthly payment:

I'm having a little trouble, as you will see...
As we know, when we do x^n - x^m
we must perform each operation on either side of the - (minus) sign, so:
x^n - x^m  =  (x^n) - (x^m)

I have developed an interest in mathematics and try to further my
knowledge by attempting as many problems as I can.
The problem given below has 'stumped' me.Some help would be appreciated.

Suppose I have an equilateral triangle inscribed in a circle of radius R.
What do I now know about the length of the sides of the triangle and about
its height?  More importantly, _how_ do I know?  I've been spending a lot of
time searching the Dr. Math website and some other ...

Please,help me!
Fermat's Little Theorem is: a^(p-1) congruent 1 mod p
when p is prime and a is not a multiple of p.  This
theorem implies that p divides 2^p-2 if p is prime.

I am looking for the formulas to calculate the internal angles of a triangle
given only the 3 side lengths:
Side A + Side B = Side C
Side A <> Side B <> Side C

Hello ladies and gentlemen,
I would like run this by you for comments to see if I am thinking this out
correctly or not thinking enough.
The problem states; "If sqrt(X - 2) and sqrt(2 - X) are both defined, then

Reading about implicit differentiation, and came upon something like this:
d[y^2]/dx = [2*y*(dy/dx)]
(This is part of a larger problem.)
In a little box to the right it says, "The chain rule was used here because

Yeah, wonderful title.
Anyway, here's the function:
y = x^3 * (5*x^2 + 1)^(-2/3)
We're to find dy/dx.  The book claims the answer is:
