Which expression is equivalent to (4 + 6i)2?

(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.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
