Question

Determine o valor de 2-¹-(-2)²+(-2)-¹/2²+2-²​

Answer 1

Resposta:

$\frac{10}{4} = \frac{5}{2}$

Explicação passo-a-passo:

2-¹-(-2)²+(-2)-¹/2²+2-²​ => $2^{-1} -(-2)^{2} +(-2) - (\frac{1}{2} )^{2} +(2)^{-2} => \frac{1}{2} -(+4) - 2 - \frac{1}{4} +\frac{1}{4} => \frac{1}{2} - 4 - 2 - \frac{1}{4} +\frac{1}{4} = \frac{1.4 + 4.4-2.4-1 +1}{4} => \frac{4 + 16-8-1 +1}{4} = \frac{10}{4} => \frac{5}{2}$
