To simplify the expression, we can start by evaluating the exponent 9^{-9}.
As the exponent is negative, we can rewrite it as 1/(9^9):
9^{-9} = 1/(9^9)
Now, we can substitute this value back into the expression:
(9−9)−2(9^{-9})^{-2}(9−9)
= 0 - 2(1/(9^9))^{-2}(0)
= -2(1/(9^9))^{-2}(0)
= -2(1/((9^9)^2))(0)
= -2(1/(9^18))(0)
= 0
Therefore, the simplified expression is 0.
