2+3і

The expression 2+3i represents the sum of 2 and 3i.

In complex numbers, i is defined as the imaginary unit, where i^2 = -1.

To find the sum, we simply add the real parts and the imaginary parts separately.

In this case, the real part is 2 and the imaginary part is 3i.

Therefore, the sum of 2+3i is equal to 2 + 3i.
