In the following lectures:
Prof. Susskind writes the terms ##\exp(3Ht_n)## and ##\exp(3ht_n)##.
If I understand correctly he computes ##R(t)=R_0 \exp[\int^{t_n}H(t')dt']## where ##R(t)## is the scale factor of the Universe and ##H(t')## is Hubble's parameter. What I still don't understand is why ##H(t')=3H##?
