To divide complex numbers, we can use the principle of multiplying by the conjugate. The conjugate of a complex number is obtained by changing the sign of the imaginary part.

In this case, we have:
(2 + 3 - 3i^3) / (1 - i)

First, let's simplify the numerator:
Since i^3 is equal to -i, we can rewrite it as:
(2 + 3 - 3(-i)) / (1 - i)
Simplifying further:
(2 + 3 + 3i) / (1 - i)

Now, we want to multiply the numerator and denominator by the conjugate of the denominator, which is (1 + i):
[(2 + 3 + 3i) * (1 + i)] / [(1 - i) * (1 + i)]

Expanding the numerator and the denominator:
[(2 + 3 + 3i + 3i + 3i^2) / (1 - i + i - i^2)]

Simplifying the numerator:
(2 + 3 + 3i + 3i - 3)
(2 + 6i)

Simplifying the denominator:
(1 - (-1))
(1 + 1)
2

Finally, putting it all together:
(2 + 6i) / 2

We can divide each term separately:
2/2 + 6i/2
1 + 3i

Therefore, the result of the division of (2 + 3 - 3i^3) / (1 - i) is 1 + 3i.
