Question

efetui A={5+[8.(3+2)-5.(8-9):5(3-(5))]-2} mim ajide desta questão por favor mim expliquem de maneira compreensível pfv​

Answer 1

{5+[8×(3+2)-5×(8-9)÷5(3-(5))]-2}

= 5 + (8)(5)-5×(8-9)÷5(3-(5))]-2}
= 5 + 40-5×(8-9)÷5(3-(5))]-2}
= 5 + 40-5×(-1)÷5(3-(5))]-2}
= 5 + 40- -5/5 (3-(5))]-2}
=5+40−−1(3−5)−2
=5+40−(−1)(−2)−2
=5+40−2−2
=5+38−2
=43−2
=41
