  1. Giải đáp:
     $1) 27.(-6)+38.(-3)-62$
    $= [27.(-6)-62]+[38.(-3)]$
    $= (-162-62)+(-114)$
    $= (-224)+(-114)$
    $= -338$
    $2) 6²= 6.6=36$
    $3) 3³= 3.3.3= 27$
     

  2. 27.(-6)+38.(-3)-62
    =-162-114-62
    =-276-62
    =-338
    6^2
    =6.6
    =36
    3^3
    =3.3.3
    =9.3
    =27
