Question

[6 x(3 x 4-2x5)- 4]+ 3 x (4 - 2) - (10 : 2) =​

Answer 1

Resposta:

[6 x(3 x 4-2x5)- 4]+ 3 x (4 - 2) - (10 : 2) =​9

Explicação passo-a-passo:

[6 x(3 x 4-2x5)- 4]+ 3 x (4 - 2) - (10 :2)

$\left(6\left(3\cdot \:4-2\cdot \:5\right)-4\right)+3\left(4-2\right)-\left(\frac{10}{2}\right)$

remover os parenteses: (a)= a

$=6\left(3\cdot \:4-2\cdot \:5\right)-4+3\left(4-2\right)-\frac{10}{2}$

$=6\left(3\cdot \:4-2\cdot \:5\right)$= 12

3(4-2)=6

10/2=5

=12-4+6-5

Somar/subtrair:

12-4+6-5

=  9
