Answer 1

3)

a) 12³⁴:12³²-3¹x3²+2³=

   12³⁴⁻³²-3¹⁺²+2³

    12²-3³+2³=

   144-27+8=117+8=125

b) 2³x3²+25⁰x11²-4⁰=                            

  8x9+1x121-1

   72+1x120

  73x120=8760                                  

c)   1+ {2+ [3x(4+5)-6+7x8]-9 }=

=1+[2+(27-6+56)-9]=

=1+[2+(21+56)-9]=

=1+(2+77-9)=

=1+(79-9)=

=1+70=

=71

d)9x { [8+7x(6+5)]x4-3}+2

9•[(8+7•11)•4-3]+2

9•[(8+77)•4-3]+2

9•(85•4-3)+2

9•(340-3)+2

9•337+2

3033+2=3035

SUCCES!!
