# 1. What is the simplified form of (–3x^3y^2)(5xy^–1)?

I think it is 15x^4y

2. What is the simplified form of –9m^–2n^5 × 2m^–3n^–6?

I have no idea on this one. :/

3. A rectangular pasture has a fence around the perimeter. The length of the fence is 16x^7 and the width is 48x^4. What is the area of the pasture?

4. What is the simplified form of (3.25 × 10^3)(7.8 × 10^6) written in scientific notation?

2.535 x 10^10 maybe?

5. The size of a certain cell is 2.5 × 10^–9 m. Another cell is 1.5 × 10^3 times larger. How large is the larger cell in scientific notation?

I think 4 x 10^-27

BTW, Please tell me the right anwsers on the ones i missed. I have tried to do this. Thanks!

2. #1
-15x^4y

#2
–9m^–2n^5 × 2m^–3n^–6?
= -18m^-5 n^-1
or
-18/(m^5n)

#3 area = length x width
= (16x^7)(48x^4)
= 768 x^11

#4 correct

#5
2.5 × 10^–9 x 1.5 × 10^3
= 3.75 x 10^-6

9. Be careful of these lists of answers without explanations. Sometimes kids deliberately post wrong answers. Sometimes teachers and/or test publishers mix the questions and answer choices up. Sometimes they change them completely!

Be aware!
