Question 169912
Could someone maybe tell me what I did wrong by these two problems; 
(3a^2b)(-2ab^3)= 6a^3b4 (why is my answer wrong?)
----------------
You lost the minus sign. It's -6a^3b^4
-----------
or why is my answer wrong here; ab^2= 3(4)^2 = 3(4*4)=48 
It would be more than great if someone could help me out here =)
--------------
I don't see a problem there.
