Question

Me ajuda aí resposta do passo a passo

Answer 1

a) 10 + [ 35 - ( 8 + 2 ) + 2 ] = 10 + [ 35 - 10 + 2 ] = 10 + [ 25 + 2 ] = 10 + 27 = 37

b) 2 + 8 - 3 - 5 + 15 = 10 - 3 - 5 + 15 = 7 - 5 + 15 = 2 + 15 = 17

c) 2 × { $2^{2}$ - [ 5 × $2^{2}$ + 7 × ( $9^{2}$ - 70)]} = 2 × { $2^{2}$ - [ 5 × $2^{2}$ + 7 × ( 81 - 70)]} =  2 × { $2^{2}$ - [ 5 × $2^{2}$ + 7 × 11 =  2 × { $2^{2}$ - [ 5 × 4 + 7 × 11]} =  { $2^{2}$ - [ 20 + 77]} = { $2^{2}$ -  97} = { 4 - 97} = -93

d) 10 + [ 30 - ( 11 + 5 ) + 5 ] = 10 + [ 30 - 16 + 5 ] = 10 + [ 14 + 5 ] = 10 + 19 = 29

espero que dê pra entender
