what is the highest possible product with a four digit number x a two digit number in which you can only use a combination of these numbers, four 9's, 8's, 7's, 6's, and 5's?

mmm maybe
9998*98 = 979804 That is my guess.
9999*88 = 879912
9988*99 = 988812 I am changing my mind, this one is bigger. :)
