Oh, you mean combinations
7!/[ 4!(7-4)!]
7! / [4!*3!]
7*6*5/3!
7*6*5/(3*2)
7*5
35
Evaluate: 7^C4
i think its something like:
(7*6*5*4*3*2*1) / ((2*1)(4*3*2*1)) = (7*6*5*4)/(4*3*2*1) = (7*6*5)/(2*1) = 105...did i do i right??

You are still writing the notation incorrectly, there is no exponent.
7C4 is what you want
also written as C(7,4)
the value is
7!/(4!3!) = 7*6*5/(3*2) = 35
or 5040/(24*6) = 35

i know i just don't know how to input it correctly on my computer :(
