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
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
