# Dealing with an exponentially debilitating problem

I can't resolve v(cubed)/exp(v)-1
which is the RHS of an equation that has been sorted out of the left!
I am rather hoping that this becomes v(cubed)/v which simplifies to v^2.

Thanks

What are you trying to express, and what are you trying to find? Are you starting with this:

$$$\frac{{v^3 }}{{e^v }} - 1$$$

Sorry for the delay in responding!
No it is the RHS of Planck's equation for B(v)T
The LHS as I have reduced it to =Bc^2/2H
