Question

½ · (-1) · (-2)2 + ¼ · (-1)2 · (-2) +3

Answer 1

Respuesta:

$\underbrace{\frac{1}{2} (-1)(-2)^2}+\underbrace{\frac{1}{4} (-1)^2(-2)}+3\\ ~~\underbrace{ \frac{1}{2}(-1)(4)} ~~~+~\underbrace{\frac{1}{4}(1)(-2)} ~+3\\ ~~~~~~\frac{-4}{2} ~~~~~~~~~+~~~~\frac{-2}{4} ~~~~~~~+3\\\\ ~~~~\underbrace{-2~~~~-\frac{1}{2} ~~+3}\\ ~~~~~~\underbrace{-\frac{2}{2} -\frac{1}{2} +\frac{6}{2} }\\ ~~~~~~~\underbrace{\frac{-2-1+6}{2} }\\~~~~~~~~~~~~\boxed {\boxed{\frac{3}{2} }}$
