The value of
is 2
The value of
+ 1 can be determined by considering the powers of the imaginary unit i
The powers of i follow a cycle:
= i,
= -1,
= -i, and
= 1. After
, the powers repeat.
Since(20 is a multiple of 4, we know that
will be equivalent to
, which is 1.
Therefore,
+ 1 = 1 + 1 = 2
So, the value of
is 2
