Answer:
23
Step-by-step explanation:
Given,
x = 3 + bị
Again,
x ÷ 2 = 13
Multiplying both the sides by 2, we can get.
(x ÷ 2) × 2 = 13 × 2
or, x = 26
As we find the value of x, we can now complete the complex number which is b.
x = 3 + bị
Putting the value of x, we can get,
26 = 3 + bi
or bi = 26 - 3
or, b = 23.
Therefore, the possible value of b = 23.
