Resolver a seguinte expressao algébrica: x=10. (24+6). 6 - 3. [ \frac{78}{5}+\frac{45}{4} ]

Answer 1

Olá Rosana, tudo bem?

Vamos lá

$x=10 \times (24+6) \times 6 - 3 \times [ \frac{78}{5}+\frac{45}{4} ]\\ x=10 \times 30 \times 6 - 3 \times [ \frac{78}{5}+\frac{45}{4} ]\\ x= 300 \times 6 - 3 \times [ \frac{78}{5}+\frac{45}{4} ]\\\\ x=1800 - 3 \times \frac{312+225}{20}\\\\ x=1800 - 3 \times \frac{537}{20}\\\\ x=1800 - \frac{1611}{20}\\\\ x= \frac{36000-1611}{20}\\\\ \boxed{ x= \frac{34389}{20} }$
