Answer:
(m+ni)2= -16 - 30i
2m + 2ni = -16-30i
.)2m=-16 .)2n=-30
m= -8 n= -15
por lo tanto.....
m2 + n2
(-8)2 + (-15)2
-16 + (- 30 )
-16 - 30
-46
respuesta..... - 46
Step-by-step explanation:
Answer:
34
Step-by-step explanation:
Given
(- 3 - 5i)(- 3 + 5i) ← expand using FOIL
= 9 - 15i + 15i - 25i² [ i² = - 1 ]
= 9 + 25
= 34
