A good way to figure this out is that "hydro" implies that the anion does not have an oxygen atom, and that you can analogize with the chlorine-based acids that you were probably given.
For example:
##"HCl"##: hydrochloric acid ##"HClO"##: hypochlorous acid ##"HClO"_2##: chlorous acid ##"HClO"_3##: chloric acid ##"HClO"_4##: perchloric acid
None of the acids above that contain oxoanions (such as ##"ClO"_3^(-)##, or ##"ClO"_4^(-)##) have "hydro" in their name.
Furthermore, the halogens all form acids with similar names because they are all in the same group/family. So, they have analogous acid naming schemes:
##"HBr"##: hydrobromic acid ##"HCl"##: hydrochloric acid ##"HI"##: hydroiodic acid
From this, you should be able to figure out that you have:
##"HBr"##: hydrobromic acid ##"HBrO"_3##: bromic acid
