Help me with this problem?

Measurements on two stars indicate that Star X has a surface temperature of 5227°C and Star Y has a surface temperature of 9627°C. If both stars have the same radius, what is the ratio of the luminosity (total power output) of Star Y to the luminosity of Star X? Both stars can be considered to have an emissivity of 1.0

em energy radiated is proportional to T^4, so it would be : ((273.15+9627)/ (273.15+5227))^4 =10.5
