Question

calculati:2³+[(2³)^7-(2^7)³+3*3⁴-81]:{3²*[301-10*(24+2^73:2^72*3)]}

Answer 1

2³ + [ ( 2³ )⁷ - ( 2⁷ )³ + 3 x 3⁴ - 81 ] : { 3² x [ 301 - 10 x ( 24 + 2⁷³ : 2⁷² x 3 ) ] } =

= 8 + ( 2²¹  - 2²¹ + 3⁵ - 3⁴ ) : { 9 x [ 301 - 10 x ( 24 + 2 ⁽ ⁷³ ⁻ ⁷² ⁾ x 3 ) ] ] =  

= 8 + 3⁴ x ( 3 - 1 ) : [ 9 x ( 301 - 10 x 30 ) ] =

= 8 + 81 x 2 :  ( 9 x 1 ) =

= 8 + 162 : 9 =

= 8 + 18 =

= 26
