    a) 57 . 115 – 57 . 15 + 57
    = 57 . (115 – 15 + 1)
    = 57 . 101
    = 5757
    b) 3^2 . {450 : [200 – (17 + 23)^5 : 50^4]} 
    = 9 . [450 : (200 – 16,384)]
    = 9 . (450 : 183,616)
    = 9 . 2,450
    ≈ 22,05690136

    = 57 ( 115 – 15 ) + 57
    = 5700 + 57
    = 5757
    b) 3^2 { 450 : [ 200 – ( 17 + 23 )^5 : 50^4 ] }
    = 3^2 { 450 : [ 200 – 16,384 ] }
    = 3^2 { 450 : 183,616 }
    = 9 . 2,450766818
    = 22,05690136
    ≈ 22
