x+7yi-4=5+21i+2

x + 7 y i - 4 = 5 + 21 i + 2

x = 11, y = 3

Solution steps

x + 7 y i - 4 = 5 + 21 i + 2

Rewrite

x + 7 y i - 4

in standard complex form:

(x - 4) + 7 y i

(x - 4) + 7 y i = 5 + 21 i + 2

Rewrite

5 + 21 i + 2

in standard complex form:

7 + 21 i

(x - 4) + 7 y i = 7 + 21 i

Complex numbers can be equal only if their real and imaginary parts are equalRewrite as system of equations:

[x - 4 = 7 7 y = 21]

[x - 4 = 7 7 y = 21] : x = 11, y = 3

x = 11, y = 3

(x + i y)^{2} + (x + i y) + 1 = 0

A = P (1 + \frac{i}{100})^{2}, i

z^{2} = 1 + i + \frac{58}{9 ( 3 - 7 i )}

(x + y i)^{2} = - 8 - 6 i

\frac{i}{- z} = \frac{2 i z}{1 + i}
