1. Đáp án:

    

   Giải thích các bước giải:

   `a) (2/3)^3=2^3/3^3=8/27`

   `b) (-2/3 )^3=-8/27`

   `c) ( -1 3/4)^2=(-7/4)^2=49/16`

   `d) (-0,1)^4=0,0001`

   `e) (-1/4)^0=1`

   `f)(0,5)^3=0,125`

   `g) (-1 1/3)^4=(-4/3)^4=256/81`

   `h) (-2 1/3)^2=(-7/3)^2=49/9“

2. `a) (2/3)³ = 2/3 . 2/3 . 2/3 = 8/27`

   `b)(-2/3)³= (-2/3) . (-2/3) . (-2/3)=-8/27`

   `c) (-1 3/4)²= (-7/4)²= (-7/4) . (-7/4)= 49/16`

   `d) (-0,1)^4= (-1/10)^4= (-1/10) . (-1/10) . (-1/10) . (-1/10)=1/1000`= 0,001

   `e)(-1/4)^0= 1` ( Vì số nào mũ 0 cũng bằng 1)

   `f)(0,5)³=(0,5) . (0,5) . (0,5)=0,125`

   `g) (-1 1/3)^4= (-4/3)^4 = (-4/3) . (-4/3) . (-4/3) . (-4/3)=256/81`

   `h) (-2 1/3)^2= ( -7/3)^2= (-7/3) . (-7/3)=49/9`
