(2/3)² 9/4 - {[3/5+(2/3)²:1/9+√25/16].4/117}

Answer 1

(2/3)² 9/4 - {[3/5+(2/3)²:1/9+√25/16].4/117} =
 4/9 . 9/4 - {[3/5 + 4/9  : 1/9 + 5/4] . 4/117} =
    36/36  - {[3/5  + 4 +5/4] . 4/117  } =
       1      - {[4.3/20 +20.4/20 +5.5/20] . 4/117} =
       1      - {[ 12 + 80 + 25/20] . 4/117 =
       1      - { 117/20 . 4/117 } =
       1 - 117/20 . 4/117 =
       1 - 468/2340 =
 2340/2340 - 5.468/2340 =
 2340 - 5468 / 2340 =
 -3128 / 2340 = simplificando por 4
 -782/585
