Question

1. x^6y^14 / x^4Y^9

Answer 1

Please, post only one or two problems at a time, and include the instructions.

Focusing on the first problem (above):  Instructions are "simplify:"

                                 x^6y^14       x^2*y^5
x^6y^14 / x^4Y^9 = ------------- = ------------- = x^2*y^5.
                                  x^4Y^9             1

Note that (x^6) / (x^4) = x^(6-4) = x^2.  Apply the same principle to y^14 / y^9.
