%change=100(final-initial)/initial
%change=100(10-4)/4=150% increase
Answer:

Step-by-step explanation:
Given number is
. We need to find the complex conjugate of the given number.
We will use the general rule to find out the complex conjugate of the number.
The complex conjugate of
will be 
And the complex conjugate of 
So, the complex conjugate of
is 
1.54-.10=1.44
