Question 32989This question is from textbook Saxon Algebra 1

: x^2/y^2-3x^2y^-2+4x^-3x^5y^-2-8y^-2/x^-2
I've tried this several times and keep getting -6x^2/y^2 but the answer is supposed to be -6x^2y^-2
Why does Saxon bring the y^2 up and make it a negative exponent?
Thank you for helping me understand this.

Question 33229This question is from textbook college algebra

: 4)For a fixed rate, a fixed principal amount, and a fixed compounding cycle, the return is an exponential function of time. Using the formula, , let r = 10%, P = 1, and n = 1 and give the coordinates (t, A) for the points where t = 0, 1, 2, 3, 4.
a)Show coordinates in this space
Show work in this space

b)Show graph here

5)Logarithms:
a)Using a calculator, find log 10000 where log means log to the base of 10.
Answer:

b)Most calculators have 2 different logs on them: log, which is based 10, and ln, which is based e. In computer science, digital computers are based on the binary numbering system which means that there are only 2 numbers available to the computer, 0 and 1. When a computer scientist needs a logarithm, he/she needs a log to base 2 which is not on any calculator. To find the log of a number to any base, we can use a conversion formula as shown here:
Using this formula, find .
