  1. Giải đáp:
     $68+(75-x)=3².2³$
    $⇔ 68+(75-x)= 9.8$
    $⇔ 68+(75-x)=72$
    $⇔ 75-x= 72-68$
    $⇔ 75-x=4$
    $⇔ x=75-4$
    $⇔ x= 71$
    $Vậy$ $x=71$
     

  2. 68+(75-x)=3^2 . 2^3
    68+(75-x)=9.8
    68+(75-x)=72
            75 – x = 72 – 68
             75 – x = 4
                  x = 75 – 4
                   x = 71
           vậy x = 71
