Question

resolva a expressão númerica
14+{5+9-[12.3+(21.5+17.3-108/9)/6]+4.9}-6.5

Answer 1

$14 + \{ 5 - 9 - [12*3 + ( \dfrac{21*5 + 17 * 3 - \frac{108}{9}}{6})]+4*9 \}-6*5 \\ \\ \\ 14 + \{ 5 - 9 - [36 + ( \dfrac{105 + 51- 12}{6})]+36\} -30 \\ \\ \\ \\ 14 + \{ 5 - 9 - [36 + ( \dfrac{144}{6})]+36\} -30 \\ \\ \\ 14 + \{ 5 - 9 - [36 + ( 24})]+36\} -30$

$14 + \{ 5 - 9 - 96 \} -30 \\ \\ 14 + \{-82 \} -30 \\ \\ 14 -112 \\ \\ => -98$

Answer 2

14+{5+9-[12.3+(21.5+17.3-108/9)/6]+4.9}-6.5
14+{14-[36+(105+51-12)/6]+36}-30
14+{14-[36+(156-12)/6]+36}-30
14+{14-[36+24]+36}-30
14+{14-60+36}-30
14-10-30
- 26
