Express the Planck radiation formula in terms of wavelength. How is this to be accomplished?

how about making the substution $$\hbar \omega = \frac{\hbar c}{\lambda}$$?

WHat is the expression that you have so far, if it is in terms of energy, $$E = \hbar \omega = \frac{\hbar c}{\lambda}$$, make the substitution and go from there.
