i have no idea what this even means
OpenStudy (shane_b):
Are you being asked to simplify:\[\frac{12p^9}{12p^8}\]
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
look at the common terms and cancel them.
OpenStudy (shane_b):
Ok, then just divided 12 by 12 to get 1...then p^9 by p^8 to get just p.

okey but the answers are either 220 4 79833600 or 19958400
OpenStudy (shane_b):
You didn't post the full question then...we have no value for p so it could be anything.
OpenStudy (anonymous):
i know but that is the question
OpenStudy (shane_b):
If that's all there is then no one can help you solve an unsolvable question...there's not enough information provided.
OpenStudy (anonymous):
or maybe the expresson is 12^p(9)/ 12^p(8)

Without knowing something about p, it can't be solved.
OpenStudy (shane_b):
It's not even an equation
OpenStudy (anonymous):

We already did that @marigirl
OpenStudy (marigirl):

OpenStudy (anonymous):

OpenStudy (shane_b):
Ok, it's a factorial notation then
OpenStudy (anonymous):

\[\frac{12*11*10*9*8*7*6*5*4}{12*11*10*9*8*7*6*5}=4\]
OpenStudy (anonymous):
It's permutations right
OpenStudy (shane_b):
Yea, all along I thought the p was just a variable
OpenStudy (anonymous):
same here lol
OpenStudy (anonymous):
Lmao
