Question

Qual a resposta?
1000(1+i)²=1268,64

Answer 1

Em anexo! Passo a passo

Answer 2

1000 (1+2i+i²)=1268,64
1000+2000i+1000i²=1268,64. |-1268,64
1000i²+2000i-268,64=0. |:1000
i²+2i-0,26864=0
$x = - \frac{ - 2}{2} + - \sqrt{( \frac{2}{2} } )^{2} + 0.26864$
$x = 1 + - \sqrt{1 + 0.26864}$
$x = 1 + - \sqrt{1.26864}$
$x1 = 2.13$
$x2 = - 0.13$
espero que esteja bem
