3 + 3i + 8 − 2i − 7
add like components:
3+8-7 -2i=4-2i
oops, I forgot the 3i, so the answer is 4+i
check that.
To simplify the given expression, you need to combine the real parts and the imaginary parts separately.
First, combine the real parts (numbers without the "i" term):
3 + 8 - 7 = 4
Next, combine the imaginary parts (numbers with an "i" term):
3i - 2i = i
Finally, put the real and imaginary parts together:
4 + i
So, the simplified form of the expression 3 + 3i + 8 - 2i - 7 is 4 + i.
