Hi

I understand most of the steps in the determination of the time scale. But i dont really understand the step in equation 6.96.

The first attachment is the full details of the time scale, and the second attachment is the part which im stuck on.

I just wanna know, how they get from the LHS to the RHS of the equation

Thanks for any help :)
