I'm not sure how it is derived.
Do we follow this order?
1. Temperature at last scattering/recombination/decoupling (3000 K)
2. Measuring the temperature of the CMB (~3K)
3. 3000K/~3K = 1100
4. z=1100
5. t(z)
Or this order?
1. Assume Big Bang and Inflation
2. Determine Volume and Pressure
3. Determine required temperature
4. Temperature at last scattering/recombination/decoupling (3000 K)
5. Measuring the temperature of the CMB (~3K)
6. 3000K/~3K = 1100
7. z=1000
5. t(z)
