(4 + 4i)/(5+4i) = divide

B.

Step-by-step explanation:

Multiplying both numerator and denominator by (5 - 4i) , the conjugate of the denominator, i. e, (5 + 4i).

Multiplying (4+4i) and (5-4i) using distributive propertyUsing the identity (a+b)(a-b)= a² - b² where 5 will act as a and 4i will act as b

i² = -1

(combining like terms)

distributing the denominator

That is, option B.
