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?
Agian IDK
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!

Do you guys need the choices?
Please help me =(
#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
-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
I don't see any math tutors online right now. You need to have patience ... and NEVER post anything that is "urgent" or "right now"!! Tutors here are volunteers, and they check in whenever they have time.
Ahhh, Reiny came in. Excellent!
okay thanks for tips and thanks for helping!
simplify 3-5n/9(1-n)*27n+1
