Question

3) Copie as expressoes numericas e determine seus valores:
c)4+{8+2x[3+(10+2x7):8]}=

Answer 1

Resposta: 4+{8+2×[3+(10+2×7):8]}= 24

Answer 2

c)
= 4 + {8 + 2 . [3 + (10 + 2.7):8]}

= 4 + {8 + 2 . [ 3 + (10 + 14) : 8]}

= 4 + { 8 + 2 . [ 3 + 24 : 8]}

= 4 + { 8 + 2 . [ 3 + 3]}

= 4 + { 8 + 2.6]}

= 4 + {8 + 12}

= 4 + 20

= 24
