What type of encryption/encoding is this? (Linux)

ive been struggling with encrypting this hash for a school homework. (backstory) i had to gain access from my Kali linux machine to a “unknown” linux machine and i’ve done it, and now i have to basically get the username and password of the unknown linux machine, i located the passwords file “/etc/shadow” and i nano’d the file to see the passwords and this came up:


The password that i need is for root, so im guessing its this one? root: $ 1$ /avpfBJ1$ x0z8w5UF9Iv./DR9E9Lid. if you’re able to decrypt it can you please explain how did you do it and what type of encryption is it?
