Question

Which of the following is equivalent to the sum 5i+3i ?(1 point) Responses −8i negative 8 i 8 8 3i+5i 3 i plus 5 i 8i2 8 i squared

Answer 1

To evaluate the sum \( 5i + 3i \), you simply add the coefficients of \( i \):

\[
5i + 3i = (5 + 3)i = 8i
\]

Thus, the equivalent expression to the sum \( 5i + 3i \) is \( 8i \).

So, the correct response from the options given is **8i**.
