I have no idea how to crack these hashes?

I've got some hashes look like this:
PT0=
PT0=

Is there any algorithm that I can use in Hashcat to crack it?

You are *NOT* allowed to post the hashes here, see: https://hashcat.net/forum/announcement-2.html
BTW: try to base64 decode them, i.e. echo -n "xyz"|base64 -d

Yep, what philsmd said. Take a week to learn the rules.
