If a number is raised to a negative power, is the answer always negative? For example, if I have 2 raised to the negative 2 power is the answer -4 or 4? Or if I have 2 raised to the -3 power, is the result 8 or -8? I'm a little rusty on my Algebra/Calcus. Please help...

Use the Gauss Jordan method to solve each system of equations.

5x-4y+2z=4
5x+3y-z=17
15x-5y+3z=25

1) Is this polynomial fully factored?
x^2- 16 = (x+4)(x-4)
Why?

2) Can you factor this polynomial
x^4 - 16 = (x^2 + 4)(x^2 - 4)

Please for number 2 question include your solution and some explanation.

Part 1: Suppose that the number of new homes built, H, in a city over a period of time, t, is graphed on a rectangular coordinate system where time is on the horizontal axis. Suppose that the number of homes built can be modeled by an exponential function, H= p * a^t , where p is the number of new homes built in the first year recorded. If you were a homebuilder looking for work, would you prefer that the value of a to be between 0 and 1 or larger than 1? Explain your reasoning.


Type formula above as H = p * a^t

Please would you help me with these questions. I don't mind if you can do all of it, some of it or just one-any amount of help will be really appreciated. i promise

1.In this question, a and b are numbers where a=b + 2
The sum of a and b is equal to the product of a and b
show that a and b are not integers

2.show that (4x10^8) x (8x10^4) = 3.2 x 10^13

3.what is (4x10^8) / (8x10^4) write answer in standard form

4.Here is information about a data set.
"There are 100 values in the set
The median is 90
The mean is 95"
i increase the highest value in the data set by 200. Now what are the median and the mean of the data set?

5.solve these simultaneous equations using an algebrating method
4x + 3y =21
2x + y = 8
show working


thanks, it's a bit of holiday homework, it was a whole 50 question booklet, i only missed out these so i really appreciate if you help me on just these few.however if you think it is wrong helping me then please don't be cruel.

For each question below, find zw and z/w. Leave your answer in polar form.

NOTE: d = degrees. Okay?

(1) z = cos120d + isin120d; w = cos100d + isin100d

(2) z = 4(cos(3pi/8) + isin(3pi/8));
w = 2(cos(9pi/16) + isin(9pi/16))
