 Examples: Simplify, x5 * x3 * x-4. Given that, x5 * x3 * x-4 Using xm * xn = xm+n We get, x5+3-4 = x4 Simplify, ((x4)-2)-2. Given that, ((x4)-2)-2 Using, ((am)n)p = (am)np = amnp ((x4)-2)-2 = (x4)-2*-2 = (x4)4 = x4*4 = x16. Simplify, x8/x4. Given that, x8/x4 Using, xm/xn = xm-n x8/x4 = x8-4 = x4 Directions: Solve the following problems. Also write at least 10 examples of your own.
