For this case we have a complex number of the form:

$a + (b) (i)\\$

Where:

a: It's the real part (b) (i)

: It is the imaginary part

Thus, given 1-8i, its complex conjugate is given by:

$1 + 8i\\$

On the other hand, the product of both is given by:

$(1 + 8i) (1-8i) =\\\\(1 ^ 2-8i + 8i-64 (i ^ 2)) =\\\\1-64 (-1) =\\\\1 + 64 = 65\\$

Conjugate complex: $1 + 8i\\$

Product: 65
