Question

Simplify this expression. Assume that x is nonzero. x^−11•x^2

Answer 1

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
