Question 1072639
49!/(5!)
= 49*48*47*46*45/5*4*3*2
simplify: divide 45 in the numerator and 5 in the denominator by 5 and you get 8/1.
Divide 48 in the numerator and 4 in the denominator by 4 and you get 12/1
Divide 46 in the numerator and 2 in the denominator by 2 and you get 23/1
Now we have:
49*12*47*23*8/1*1*3*1
One more, divide 12 and 3 by 3:
49*4*47*23*8/1*1*1*1 = 49*4*47*23*8 = 1,695,008
