  1. Answer
    A = (1/3)^{3} . 3^{3} + 0,75 . (-2)^{2} + (-0,15)^{0} + 4 . \sqrt{0,25} + \sqrt{(-5)^{2}}
    A = 1/27 . 27 + 3/4 . 4 + 1 + 4 . 1/2 + 5
    A = 1 + 3 + 1 + 2 + 5
    A = 4 + 1 + 2 + 5
    A = 5 + 2 + 5
    A = 7 + 5
    A = 12

  2. A=(1/3)^3.3^3+0,75.(-2)^2+(-0,15)^0+4.$\sqrt{0,25}$+$\sqrt{(-5)^2}$
    A=1/27.27+0,75.4+1+2+5
    A=1+3+1+2+5
    A=4+3+5
    A=7+5
    A=12
    Vậy A=12
