calculati:(3^3:3^2+12^1:3^1-2014^0):[27^0+2^3-2^1-144:12^2
​

Answer 1

(3³:3²+12¹:3¹-2014^0):[27^0+2³-2¹-144:12²] =

= (27:9+12:3-1):[1+8-2-144:144] =

= (3+12:3-1):[1+8-2-144:144] =

= (3+4-1):[1+8-2-144:144] =

= (7-1):[1+8-2-144:144] =

= 6:[1+8-2-144:144] =

= 6:[1+8-2-1] =

= 6:[9-2-1] =

= 6:[7-1] =

= 6:6 =

= 1
