  1. |-2| . \sqrt{0,25} + (-3)^3+1/9 + (-2009)^0 . (-1)^2009
    =  2 . 0,5 + (-27) + 1/9 + 1 . (-1)
    =  1 – 27 + 1/9 – 1
    = -242/9

    Chúc bạn học tốt!!
    |-2|. √0,25+(-3)³+$\frac{1}{9}$ +$-2009^{0}$ .$-1^{2009}$  
    =2.0,5+(-27)+$\frac{1}{9}$+1.(-1)
    =1+(-27)+$\frac{1}{9}$+(-1)
    =(-26)+$\frac{1}{9}$+(-1)
    =(-27)+$\frac{1}{9}$
    =$\frac{-243}{9}$+$\frac{1}{9}$
    =$\frac{-242}{9}$
