Answer:
Step-by-step explanation:
I'm assuming that you meant: x^(-11)*x^2. Here there's a common base: x.
Then this expression becomes x^(-11*2)*x^2. We need only combine (add up) the exponents of x: x^(-11*2)*x^2 = x^(-11 + 2) = x^(-9). Use of parentheses as shown is important here.
Note that x^(-9) is the same as
1
------------
x^9
You're right ^^ if u wanna know why, I can answer it for u :)
*edit* I used the wrong your XD
126
A=(3*-1)-(2*0)= -3
B=(3*2)-(6*8)=-42
AB= (-3)*(-42)=126 :)
