Real vs Average Power: Which is Correct?

[influx]

So I was reading through my course's lecture slides and it appears to contradict.

In one slide it states that the average power, P = V_rmsI_rmsCos(phi)

in another slide it states that the real power, P = V_rmsI_rmsCos(phi)

Which one is correct?

Since the rms value is the average value, and they are used to calculate real power.. the equation is calculating average real power
