Question 130502
(-y)^-8/6(y)^5      To raise a power to a power ---Multiply exponents. If you 
                    do not see exponent, it is one.
1/6y^5(-y^8)        Move the term in the numerator with the negative exponent
                    to the denominator.   Changing sides of the fraction line
                    changes the sign of the exponent.
1/-6y^13            Multiply the coefficients of the variables first.
                    Then multiply the y terms together.   Remember,to 
                    multiply like bases, you add the exponents.
