7 x { 7 + 7 x [ 7⁶ - ( 7² ) ³ + 11 ] } + 2 x 7² - 3 x 23 = 617
= 7 x [ 7 + 7 x ( 7⁶ - 7⁶ + 11 ) ] + 2 x 49 - 69 =
= 7 x ( 7 + 7 x 11 ) + 98 - 69 =
= 7 x ( 7 + 77 ) + 98 - 69 =
= 7 x 84 + 29 =
= 588 + 29 =
= 617

( 9 + 3⁴ : 9² ) : 10 + 81 x 82 : 41 : 3³ - ( 2013²⁰¹⁴ ) ⁰= 6
= ( 9 + 3⁴ : 3⁴ ) : 10 + 81 x 82: 41 : 27 - 2013 ²⁰¹⁴ ˣ ⁰ =
= ( 9 + 1 ) : 10 + 3 x 2 - 2013⁰ =
= 10 : 10 + 6 - 1 =
= 1 + 6 - 1 =
= 6

18 176 : 71 - 3 x ( 29 x 24 - 23 x 30 ) + 11⁷ : 11⁵ = 359
= 256 - 3 x ( 696 - 690 ) + 11 ⁽ ⁷ ⁻ ⁵ ⁾ =
= 256 - 3 x 6 + 11² =
= 256 - 18 + 121 =
= 238 + 121 =
= 359

( 84 084 : 42 + 13 ) : 403 + 9 x [ 85 085 : 11 - 3 x ( 73 x 16 - 1 143 ) ] = 68 945
= ( 2002 + 13 ) : 403 + 9 x [ 7 735 - 3 x ( 1 168 - 1 143 ) ] =
= 2 015 : 403 + 9 x ( 7 735 - 3 x 25 ) =
= 5 + 9 x ( 7 735 - 75 ) =
= 5 + 9 x 7 660 =
= 5 + 68 940 =
= 68 945
