12 points From input bits p, q, and r,
construct a combinatorial
circuit using NOT gates, OR
gates, and AND gates that
produces the output below.
(Note: Take a picture of your
final answer and upload it), *
((PV-r)^-^) (p^(q V r))

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

answer is  

a.

5.56

hope you get this right.
