You just multiply your current powerlevel according to your required multiplier. According to http://dragonballzroleplaying.wikia.com/wiki/How_to_Role_Play#XP_Points, And so on...
 * Levels 1-5: +1 Speed and Damage, +2,000 Health, and Power Level X3
 * Levels 6-25: +2 Speed and Damage, +4,000 Health, Power Level X2, and  Z  2,000
 * Levels 26-50: +5 Speed and Damage, +10,000 Health, Power Level X1.5, and  Z  5,000

Seeing that your character, Drake, is level 4 so your current powerlevel (The one which is already there at your playercard) will be multiplied by X3.

P.S: I'm a playercard editor here, you may ask me to edit your playercard if you need help leveling up.

Thank you.
