Hi! For this question it asks to simplify, the problem is: a^-3 b^2.
What I got for this was ab^1. Please help me Thank You=)
-(3-10)-(6-3)
My answer is not coming out correctly.
Please see my version-
-(3+(-10))-3=
-(-7)-3=
-(-7)+(-3)= -13
The textbook gives the answer as 4. Where am I going wrong?
Thank you.
