Question

(-2)^3 + 10 · [(-1)^2018 + (-1)^2019 +2. (2.3 - 2)]

Answer 1

Răspuns: $\red {\Large\boxed{\bf 72}}$

Explicație pas cu pas:

$\large\bf (-2)^{3} + 10 \cdot [(-1)^{2018} + (-1)^{2019} +2\cdot(2\cdot3 - 2)]=$

$\large\bf (-2)^{3} + 10 \cdot [+1-1 +2\cdot(6 - 2)]=$

$\large\bf (-2)^{3} + 10 \cdot (2\cdot 4)=$

$\large\bf -8+ 10 \cdot 8=$

$\large\bf -8+ 80=$

$\red {\Large\boxed{\bf 72}}$
