Question

√−16 − √49 − ̅̅̅̅̅̅̅̅̅̅ (3;−2) + [√2 . (cos45° + i sen 45°)]

Answer 1

Respuesta:

$5i$

Explicación paso a paso:

Recuerda que $i=\sqrt{-1}$

$\sqrt{-16} -\sqrt{49} -(3 . -2) + [\sqrt{2} .(cos45$°$+ isen45$°)]

$4i-(7)-(-6)+ [\sqrt{2} .((\frac{\sqrt{2} }{2}) +i(\frac{\sqrt{2} }{2}))]$

$4i-7+6+[1+i]$

$4i -1 +1+ i$

$5i$
