I have two questions.

The first is 24=e(x+1).....where x+1 is an exponent. I know its very simple but i just can't remember how to solve it.

The second is log(4)x=3/2....where 4 is the subscript.

Any suggestions would be helpful.

In an article in the Journal of Management, Morris, Avila and Allen studied innovation by surveying firms to find the number of new products introduced by the firms. A randon sample of 100 California firms are selected. Each firm is asked to report the number of new products introduced last year. The survey found that on average, these firms introduced 5.68 products with a standard deviation of 8.70. Compute a 98% confidence interval for the new products introduced last year.

How do you find the values of x and y?
100 = 6x+7y. where x+y=15?

I know the answers, but can't do the figuring. I need to apply this formula to other equations and need to know how to "do the work". Thanks in advance!

The properties should be used are:
1) Distributive Property
2) Additive Inverse Property
3) Multiplicative Identity Property
4) Multiplication Property Of Zero
5) Cancellation Property Of Addition

Please answer this question because the answers given in my last question was not correct.
The proving should start with the equation:
(-1)a = -a
And should end also in the equation:
(-1)a = -a
Please answer on or before Sunday, August 26, 2007 on any time zone.

I'm having a tough time with three different problems. Thanks for your help!

1. In the equation (1/5)^m x (1/4)^8 = 1/(2(10)^35), what is m? According to the book, m=35. Could you please explain how they got that answer?

2. Two circles with a diameter of 1 are connected by 15 ft. conveyer belt. What is the distance between the centers of the two circles. The answer is supposed to be (15-pi)/2. Please explain.

3. Finally, I'm having problems with addition and subtraction of numbers with exponents. For example, 10^8-10^2 / 10^7 - 10^3. The answer is 10, but is there an easy way to solve this question w/o multiplying it all out on a calculator?

Thanks for your help!
