The problem should be mentioned more clearly. Is it (8!/6!)*2! or 8!/(!6*!2)? If it is (8!/6!)*2! Then the solution: 8! = 8x7x6x5x4x3x2x1, 6! = 6x5x4x3x2x1, 2!=2. So, (8!/6!)*2! = 56x2 = 112. If it is 8!/(6!*2!) The the solution: 8! = 8x7x6x5x4x3x2x1, 6! = 6x5x4x3x2x1, 2!=2. So, 8!/(6!*2!) = 56/2 =...

The problem is not clear. If we consider the problem as (8!/6!) * 2! we can proceed like this: 8! can be written as 8*7*6!. 6! can be cancelled both in the numerator and denominator. We are left with 8*7*2 ( since 2! = 2*1 =2) = 112. If we consider the problem as 8!/(6!*2!). we get 28.
