I have a resistor with a voltage across it and and a current through it that satisfy the passive sign convention.

the problem wants me to write three different ways in which the power dissapated by the resistor can be calculcated.

i know Ohms law v=ir
and watts law p=iv but i dnt understand what to do next

P=VI

P=I^2R

P=V^2/R
I^2 R
VI
V^2/R
