a) 3³-3³÷(2⁶-2⁵-2⁴-2³-2¹-2⁰) =18

2⁶=64 ; 2⁵=32 ; 2⁴= 16 ; 2³=8 ; 2¹=2 ; 2⁰=0 ;3⁴=81 ;3²=9

1)64-32=32

2)32-16=16

3)16-8=8

4)8-2=4

5)4-0=4

6)81-9=72

7)72÷4=18

b) (5⁷+5⁶+5⁵)÷5⁵+9⁷÷3¹⁰=122

5⁷=78.125 ; 5⁶= 15.625 ; 5⁵= 3.125 ; 9⁷=4.782.969 ; 3¹⁰= 59.049

1)78.125+15.625=93.750

2)93.750+3.125=96.875

3)96.875÷3125=31

4)4.782.969:59.049= 81

4)31+81=122
