What would be the absolute magnitude of a main sequence star with a temp. of 25,000 degrees Kelvin? Plz help I'm tired and want to go to bed?

The luminosity of a particular star is proportional to the fourth power
of the ratio between that star's temperature and the temperature of
Ts = temperature of the sun = 6,000 K
Tx = temperature of main sequence star = 25,000 K
Ls = luminosity of the sun = 1
Lx = luminosity of main sequence star = to be determined
Lx = (Tx / Ts)^4 = (25,000 K / 6,000 K)^4 = 4.166666667 ^4 = 301

Literally, I googled this and found an HR chart showing the absolute luminosity versus temperature which is also I bet in your textbook. Maybe you need an easier course, like 'future careers in fast food'.
