Question: Evaluate: (8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)(5 x 4 x 3 x 2 x 1)( 3 x 2 x 1) )


A ) 40
B ) 46
C ) 56
D ) 48

Steps to derive

1 (8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)(5 x 4 x 3 x 2 x 1)( 3 x 2 x 1) .
 [Cancel the common factors.]

2 = (8 x 7 x 6)(3 x 2 x 1) = 56



Hence the right answer is Option C
