Answer:

Step-by-step explanation:
We want to write the conjugate of the complex number:

Recall that the conjugate of a complex number in the form <em>a</em> + <em>b</em>i is <em>a</em> - <em>b</em>i, and vice versa.
We can rewrite our complex number as:

Hence, <em>a</em> = 0 and <em>b</em> = 6.
Then its conjugate will be:
