$|A>=a|c>+b|d>$
where a and b are complex numbers.
So, is it correct to say that
$<A|=a^{*}<c|+b^{*}<d|$
?

Regards.

for sure. you should get a quantum text book though for these types of questions. Griffiths, Balentine, Mesiah, Sakurai they are all good and have answers to those types of questions everywhere.
