Question on deannualizing for derivatives

On certain occasions, you multiply a rate by x/365 and sometimes you bring it to a power (1.06)^x/365 it gets confusing which one you have to do when memorizing all these forward valuation formulas. does anyone know what the intuition behind this is so its clearer? Thanks,

LIBOR usually x / 360 or 360 / x convention. Futures part - I seem to remember as x/365 convention.

guys, sorry, but i was asking when you multiply, or raise it to a power. not the 360 365 thing.
