To simplify this expression, we first need to find the cube of 3i:
(3i)^3 = 3i 3i 3i= 27i^3= 27(-i)= -27i
Now, we can substitute this back into the original expression:
(-27i) - 4i + 2= -27i - 4i + 2= -31i + 2
Therefore, (3i)^3 - 4i + 2 simplifies to -31i + 2.
To simplify this expression, we first need to find the cube of 3i:

= 27i^3
= 27(-i)
= -27i
Now, we can substitute this back into the original expression:
(-27i) - 4i + 2
= -27i - 4i + 2
= -31i + 2
Therefore, (3i)^3 - 4i + 2 simplifies to -31i + 2.
