So now you are superposing power to "yield" a resultant power.
I see you corrected your English. :-) The answer is NO, powers
cannot be superposed. There is a specialized equation for adding
powers and it is *NOT* a superposition equation. Born and Wolf
call it the "total intensity" equation with an included
"interference" term. Their words, not mine.
The equation also appears in Dr. Best's QEX article of Nov/Dec
2001 and in "Optics", by Hecht.
