Question

6) Determine o valor desta expressão:
(-1)²-(-1)^4 +(-2)² - 2²+(-1-1)²​

Answer 1

Resposta:

$( - 1) {}^{2} - ( - 1) {}^{4} + ( - 2) {}^{2} - 2 {}^{2} + ( - 1 - 1) {}^{2}$

$= 1 - 1 + ( - 2) {}^{2} - 2 {}^{2} + ( - 2) {}^{2}$

$= 2 \times ( - 2) {}^{2} - 2 {}^{2}$

$= 2 \times 2 {}^{2} - 2 {}^{2}$

$= 2 {}^{2}$

$4$

$\boxed{\boxed{\boxed{\boxed{RESPOSTA:4}}}}$
