  1. Lời giải và giải thích chi tiết
    16.61+38.16+16
    =16.61+38.16+16.1
    =16.(61+38+1)
    =16.100=1600
    5^2-36:3^2
    =25-36:9
    =25-4=21

  2.    16. 61 + 38. 16 + 16
    = 16. (61 + 38 + 1)
    = 16. 100
    = 1600
    ______________
        5^2 – 36 : 3^2
    = 25 – 36 : 9
    = 25 – 4
    = 21
