Answer:
(4 + 6i)² = -20 + 48i
Step-by-step explanation:
Here given square of complex number that is:
(4 + 6i)²
Now use the square property :
(a + b)² = a² + b² + 2ab
(4 + 6i)² = 4² + (6i)² + 2(4)(6i)
(4 + 6i)² = 16 + 36i² + 48i
(4 + 6i)² = 16 - 36 + 48i (value of i² = -1)
(4 + 6i)² = -20 + 48i
That's the final answer.
I hope its help you.
