Question

{2 x 3 la puterea 2 - 3 la puterea 2 + 3 x [3+3 x (3 la puterea 3 - 3 la puterea 5 :3 la puterea 3)]} : (2017 la puterea 0 + 0 la puterea 2017 + 2 la puterea 1

Answer 1

{ 2 x 3² - 3² + 3 x [ 3 + 3 x ( 3³ - 3⁵ : 3³ ) ] } : ( 2017⁰ + 0²⁰¹⁷ + 2¹ ) = 60

= { 2 x 9 - 9 + 3 x [ 3 + 3 x ( 27 - 3 ⁽ ⁵ ⁻ ³ ⁾ ) ] } : ( 1 + 0 + 2 ) =

= { 18 - 9 + 3 x [ 3 + 3 x ( 27 - 3² ) ] } : 3 =

= [ 9 + 3 x ( 3 + 3 x 18 ) ] : 3 =

= [ 9 + 3 x ( 3 + 54 ) ] : 3 =

= ( 9 + 3 x 57 ) : 3 =

= ( 9 + 171 ) : 3 =

= 180 : 3 =

= 60
