Answer 2

{ 16 + 4 × [ 8 × 2 : 4 + 12 × 6 × ( 42 : 7 : 3 + 4 × 9 : 6 ) ] } : ( 83 - 81 ) = 1 168

= { 16 + 4 × [ 16 : 4 + 72 × ( 6 : 3 + 36 : 6 ) ] } : 2 =

= { 16 + 4 × { 4 + 72 × ( 2 + 6 ) ] } : 2 =

= [ 16 + 4 × ( 4 + 72 × 8 ) ] : 2 =

= [ 16 + 4 × ( 4 + 576 ) ] : 2 =

= ( 16 + 4 × 580 ) : 2 =

= ( 16 + 2 320  ) : 2 =

= 2 336 : 2 =

= 1 168
