Hi,
A Power Chord is a chord that consist of the root and the fifth.
For example, to play a F Power Chord, you press the F note (root) and the C note (5th).
Now the exercise below is a triplet slap exercise.
---------5(p)--------7(p)---------9(p)-------
--0-(h)3------0-(h)5------0-(h)7------------
----------------------------------------------

Practice slowly and gradually increase the speed.
Have Fun.
