*Please explain on how to do each of these!

1. Let (x) be defined for all positive integer values of x as the product of all even factors of 4x. For example, (3)=12x6x4x2=576. What is the value of (5)? Someone says that it is f(5)= 20x10x2x4=1600 I DO NOT GET HOW THEY ARRIVED THAT ANSWER!

2. 2.3 ^5 log(is raised at the same level as 5 meaning not above 5) base 2.3 ^1

The answer is 1 but I do not get how?

3. If p and q are two different prime numbers greater than 2, and n=pq, how many positive factors, including 1 and n, does n have?

Do not get how the answer is 4!!!!????

4. How do you put this in a TI-83 graphing calc?

A= 9 -3 1

1 1 1

16 4 1

Matrix A is 3x3

X= x

y

z

Matrix X is a 3x1

B= -7

-3

21

Matrix B is 3x1
