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

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

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
