Please help with the following problems. I need more detail on each problem how the solution was achieved using these steps.

Thanks for your help.

2. Find the product: (x - 2)(x + 3)(x - 4)
(x - 2)(x + 3)(x - 4) =

3. Simplify without having negative exponents: (- 3s-3t2)-2
(- 3s-3t2)-2

4. Convert to scientific notation and then solve. Give answer in scientific notation: (0.0000003)4

5. Factor completely: 3a3b - 3ab3
3a3b - 3ab3

13. For a certain time period the ratio of the dollar value of exports to the dollar value of imports for the United States were 2 to 3. If the value of exports during that time period was 48 billion dollars, then what was the value of imports?

Solution. I Assume that the value of imports was x dollars. Then I have (SEE ATTACHMENT)

So, the value of imports was 72 billion dollars.
