. In the video 'Exponent Rules Part 1' - we are given . . the example - 2 to the 9th , over 2 to the 10th , Mr..
. Khan works the problem , and then states that arriving 'here' ( at this problem ) we should have been . . exposed to flipping the exponent in the denominator 2 to the 10th , into the numerator as a " . . . "Negative Exponent " - Mr. Khan further states that ' 'I' should know this from Level 2 Ex
ponents " -

Where EXACTLY do I go to review this , also , I
need extra problems on this concept before I'm ready to move on towards my goal - Radicals -
