Song Help Request Lithium - Nirvana

[a_vehicle]

Hi,
I'm awfully loving Nirvana's "Lithium", but I'm a very beginner on the Uke and I don't really know how to play the chords!
The main Chords should be
Em G# C#5 A C5 D5 B5 D5
Em is clear to me, G# also, but what are these "5" chords? How do i play them? I've searched the Internet for so long, but I didn't find an answer.
There is even a Youtubevideo with the song, but I don't know how to play:

Please help a desperate Uke-mate!

The fifths are also called "power chords," which are pretty common in rock. They consist of only the root note and the fifth and usually stay within one octave. So a C5 is C and G only, which you might play as X033.

Look up what notes make up the major scales and find a chart of the fretboard and the chords will become easy to map out.
