Answer:
The expression (1 + 3i) + (2 − 5i) is equivalent to 3 -2i .
Option (B) is correct .
Explanation:
As the expression given in the question be.
= (1 + 3i) + (2 − 5i)
Open the bracket
= 1 + 3i + 2 - 5i
Simplify the above
= 1 + 2 + 3i - 5i
= 3 -2i
Therefore the expression (1 + 3i) + (2 − 5i) is equivalent to 3 -2i .
Option (B) is correct .
