Answer 1

Respuesta:

Explicación paso a paso:

1- a) z + w

(-5 + 4i) + (2 - 3i) = -5 + 4i + 2 - 3i = (-5 + 2) + (4i - 3i) = -3 + i

c) (-3 - 2i) + (-5 + i) = -3 - 2i - 5 + i = (-3 - 5) + (-2i + i) = -8 - i

e) (5 - 2i) + (6i) = 5 + (-2i + 6i) = 5 + 4i

2- $\frac{z}{w}$

z = 3, w = 2 + 4i

$\frac{3}{2+4i}$ = $\frac{3}{2} +\frac{3}{4}i^{-1}$

z = 2 + 9i, w = -3 - i

9i + 2  ÷ -i - 3

-9i - 27    -9

     -25

$\frac{2 + 9i}{-3-i}$ = $9+\frac{-25}{-3-i}$ = $9+\frac{25}{3} -\frac{25}{i}$ = $\frac{52}{3} -25i^{-1}$
