Evaluate each expression..
please help with these.. thank you
29. 4! = 4*3*2*1 = 24
-------------------------

30. 8i/6i 2i
Is the 2i a factor in the denominator?
Please use parentheses
----------------------------------


31. 6C3 = 6!/[(6-3)!*3!] = (6*5*4)/(1*2*3) = 20
----------------------------------

32. 7P2 = 7!/(7-2)! = 7!/5! = 7*6 = 2
---------------------------------
