Respuesta :
a + bi is the standard form of a complex number.
You would treat complex numbers just like any other numbers a far as adding and subtracting like terms.
9 + 6i - 1 - 3i = 8 + 3i Letter C is the answer

Answer:
option (c) is correct.
(9 + 6i) − (1 + 3i) in standard form is 8+3i
Step-by-step explanation:
Given : (9 + 6i) − (1 + 3i)
We have to write the given complex number in standard simplified form.
Consider the given complex number (9 + 6i) − (1 + 3i)
Grouping the real part and the imaginary parts
[tex]\left(a+bi\right)\pm \left(c+di\right)=\left(a\:\pm \:c\right)+\left(b\:\pm \:d\right)i[/tex]
We get,
[tex]=\left(9-1\right)+\left(6-3\right)i[/tex]
On simplifying , we get,
[tex]=8+3i[/tex]
Thus, option (c) is correct.
