Step-by-step explanation:
t = 4
u = 6 + 2
Find t - u
solu
t - u
= 4 - ( 6 + 2 ) = 4 - 8
Answer is -4
The value of t-u is -2(1+i).
The complex number is basically the combination of a real number and an imaginary number.
For the subtraction of two complex numbers we subtract real part from the real and imaginary from imaginary.
According to the given question.
We have two complex numbers
t = 4 + 0i and u = 6 + 2i
Therefore,
[tex]t - u = 4+ 0i - ( 6 + 2i)[/tex]
⇒[tex]t - u = 4 + 0i - 6 - 2i[/tex]
⇒[tex]t - u = -2 -2i[/tex]
⇒[tex]t - u = -2(1+i)[/tex]
Hence, t - u = -2(1 + i).
