Hey guys, sorry if I'm wasting your time, but isn't a negative exponent, multiplied by a positive exponent, supposed to end up as a negative exponent if it ends up as an odd number, but otherwise ends up positive?

How can ^-12 x ^9 be ^-108 while,
while ^7 x ^9 also end up at ^-63?

Isnt that inconsistent with the rule?
