The sum \( 5i + 3i \) can be combined as follows:
\[
5i + 3i = (5 + 3)i = 8i
\]
So, the equivalent expression for the sum \( 5i + 3i \) is \( 8i \).
Therefore, the correct response is:
**8i**
\[
5i + 3i = (5 + 3)i = 8i
\]
So, the equivalent expression for the sum \( 5i + 3i \) is \( 8i \).
Therefore, the correct response is:
**8i**

The equivalent to the sum \( 5i + 3i \) is \( 8i \).
Among the options provided:
- \( 3i + 5i \) is equivalent but not simplified.
- \( -8i \) is incorrect.
- \( 8 \) is incorrect.
- \( 8i^2 \) is incorrect since \( i^2 = -1 \), making \( 8i^2 = -8 \).
So, the best choice from your options is **8i** (though not explicitly listed as such, \( 3i + 5i \) simplifies to \( 8i \)).
