Dovator [93]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{8 + 8i}}}}}$

Option D is the correct option.

Step-by-step explanation:

$\sf{(3 + i) + (5 + 7i)}$

When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.

That means, the expression remains the same.

Just remove the unnecessary parentheses

⇒ $\sf{3 + i + 5 + 7i}$

Collect like terms and simplify

⇒ $\sf{3 + 5 + i + 7i}$

⇒ $\sf{8 + 8i}$

Hope I helped!

Best regards!!
