Hi, can anybody help me with this problem?

Planck's law of radiation for a blackbody radiator quantifies the relation between it's radiative flux and wavelength at a particular temperature.

given by:

F(w)=C1/[w^5(exp(C2/wT)-1]

where, w=wavelength, C1 and C2 are constants and T is the absolute temperature.

My problem is , I have to show that the peak radiative flux of the Planck spectrum varies as the fourth power of temperature.

Do i need to do some integration of Plancks law to show this?

If so, where do i start?
