How to make plot for this equation

Hi! I try to make plot for this equation :

With this numerical example :

I try to input in in mathematica software but the plot did not show up. Is there anything wrong with my code?

If you do not put a space between L and V and between V and t then Mathematica thinks that you have a new variable named LVt

f[θ_]:=w(Log[θ]/Log[2])^2+2 L V t^(Log[θ]/Log[2])/(2-p)
(*or*)
f[θ_]:=w(Logθ]/Log[2])^2+2 L*V*t^(Log[θ]/Log[2])/(2-p)

You are right, it work now! Thank you so much
