To express the given complex number i9 + i19 in the form a + ib, we can combine the real and imaginary parts.

The real part is obtained by adding the real parts of the two complex numbers, which in this case is 0 + 0 = 0.

The imaginary part is obtained by adding the imaginary parts of the two complex numbers, which in this case is 9 + 19 = 28.

Therefore, the complex number i9 + i19 can be expressed as 0 + 28i.
