Answer 1

Answer:

a=1 and b=0

Step-by-step explanation:

The given equation is:

(\frac{1-i}{1+i})^{100}=a+ib(

1+i

1−i

)

100

=a+ib

Upon solving the above equation, we get

(\frac{1-i}{1+i}{\times}\frac{1-i}{1-i})^{100}=a+ib(

1+i

1−i

×

1−i

1−i

)

100

=a+ib

(\frac{1+i^2-2i}{2})^{100}=a+ib(

2

1+i

2

−2i

)

100

=a+ib

(\frac{1-1-2i}{2})^{100}=a+ib(

2

1−1−2i

)

100

=a+ib

(-i)^{100}=a+ib(−i)

100

=a+ib

(-i^2)^{50}=a+ib(−i

2

)

50

=a+ib

1=a+ib1=a+ib

Thus, on comparing, a=1 and b=0.
