  1. @ ????????????????????????✨
    Bạn tham khảo ~
    a) 103-11.(5-8)
    =103-11.(-3)
    =103-(-33)
    =136
    b) [168-(46+254):15]-200
    =[168-300:15]-200
    =[168-20]-200
    =148-200
    =-52
    c) 3^9.3:3^10+2^5:2^4.2^2-9.2014^0
    =3^10:3^10+2^3-9.1
    =1+8-9
    =0

    Lời giải và giải thích chi tiết:
    $103-11.(5-8)\\=103-11.(-3)\\=103-(-33)\\=136\\ [168-(46+254):15]-200\\=(168-300:15)-200\\=(168-20)-200\\=148-200\\=-52\\3^9.3:3^{10}+2^5:2^4.2^2-9.2014^0\\=3^{10}:3^{10}+2.2^2-9.1\\=1+2.4-9\\=1+8-9\\=9-9\\=0$
