alguém poderia me ajudar com essas questoes ?

Answer 1

a) =(34)2⋅(−2)3+(−12)1

a=(34)2⋅(−2)3+(−12)1

=(34)2⋅(−23)−12

a=(34)2⋅(−23)−12

=−916⋅23−12

a=−916⋅23−12

=−924⋅23−12

a=−924⋅23−12

=−92−12

a=−92−12

=−5

b)

=(12)−2+(13)−1

b=(12)−2+(13)−1

=22+3

b=22+3

=4+3

b=4+3

=7

c) =−2⋅(32)3+115−(−2)1

c=−2⋅(32)3+115−(−2)1

=−2⋅278+1−(−2)

c=−2⋅278+1−(−2)

=−274+1+2

c=−274+1+2

=−274+3

c=−274+3

=−154

c=−154
