Step-by-step explanation:
Let's look at our expression:
[tex]1.7+8.23-3.4+4.7j[/tex]
The numbers without a variable at the end are like terms here. Let's add them up.
[tex]1.7+8.23=9.93\\9.93-3.4=6.53[/tex]
Then, let's add our answer, 6.53, to the term with a variable, 4.7j.
Our final answer: 6.53 + 4.7j
I hope this helps you!
