simplify and write with only positive exponents 1. x to yhe negitive six power times x to the fifth power 2. y to the negitive twelth power divided by 7y to the fifth power

algebra 
Kathleen,
X^6 times X^5= X^1 (add exponents
6 + 5=1
X to the negative 1 can be rewritten 1/X
so you have only postitve exponents.
Y^12 divided by Y^5 = Y^17 (subtract
exponents 125=17)
So Y^17=1/Y^17
