once again, what are you asking?
how is this simplified
Whenever you have anything raised to the negative power, flip it upside down. So:
X^-1 = 1/X
X^-3 = 1/(X^3)
Whenever anything is raised to the 1 power, it is itself.
X^1 = X
12398719283719^1 = 12398719283719
Whenever anything is raised to the 0 power, it is 1.
X^0 = 1
12398719283719^0 = 1
