Answer:
(a)
Multiplicative inverse of w will be
(B) As w is same as the product of
So there multiplicative inverse will also be same
Step-by-step explanation:
We have given two complex numbers
and
(a) First we have to find
So
As we know that
So
Multiplicative inverse :
It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1
So multiplicative inverse of w will be
Because when we multiply with
it gives result as 1
(b) As w is same as the product of
So there multiplicative inverse will also be same
