I don't know what to do but I think it is #1
11/16/9= is 11÷16÷9 which is approximately 0.076
It’s $18.63 , 10.35 divided by 5 = 2.07 , so 2.07 times 9 = $18.63
we know that
The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign
so
In this problem we have

the conjugate is equal to--------> 
therefore
<u>the answer is the option</u>
10+3i
