17 + (-4) - 4/5j-2/5j+6

19 - (6/5) j

Step-by-step explanation:

In this expression we have addition, subtraction and multiplication.

According to order of operations rules, mult. and div. must be carried out before add. or subt.

Therefore, we begin with 17 + (-4), which becomes 17 - 4, or 13.

Next we see - 4/5j, by which I assume you mean - 4/5 * j.

Summarizing what we have so far:

13 - (4/5) j - 2/5j + 6

Combining the j terms, we get

13 - (6/5) j + 6, which collapses to 19 - (6/5) j.
