( - 2 i 2009 - i 2011 ) - 1 , 000 , 001 = ( - 2 i - ( - i )) - 1 , 000 , 001 = ( - i ) - 1 , 000 , 001 = ( - 1) - 1 , 000 , 001 ( i ) - 1 , 000 , 001 = - 1 ( i ) 1 , 000 , 001 = - 1 i · - i - i = i 2. We are given the following: A and B are subsets of the universal set U ; n ( U ) = 25, n ( A ) = 22, n ( B ) = 21, and n ( A B ) = 23. n ( A B ) = n ( A ) + n ( B ) - n ( A B ) n ( A B ) = n ( A )+ n ( B ) - n ( A B ) = 22+21 - 23 = 20 n (( A B ) 0 ) = n ( U ) - n ( A B ) = 25 - 20 = 5 ( (( A B ) 0 )) = 2 n (( A B ) 0 ) = 2 5 = 32 III. (2 x 2 - 4 8) 4 = (2 x 4 ) 4 - 4(2 x 4 ) 3 ( 4 8) + 6(2 x 4 ) 2 ( 4 8) 2 - 4(2 x 4 )( 4 8) 3 + ( 4 8) 4 = 16 x 16 - 4(8 x 12 )( 4 8) + 6(4 x 8 )(2 2) - 4(2 x 4 )(4 4 2) + 8 = 16 x 16 - 32 x 12 4 8 + 48 x 8 2 - 32 x 4 4 2 + 8 IV.
