Henderson Hasselbalch solubility question

Hello everyone,
I am having trouble understanding the problem in the attached photo. Does anyone know how the answer was actually calculated ? They have simply stated the answer but no explanation as to how they arrived at this. Any help would be greatly appreciated.

Well, what do you know about the quotient of the Henderson-Hasselbalch equation (the logQ part)? You know how many ions are dissociated (the solubility) at a pH of 8.0, what else forms the quotient?

If I had the equation x = log 100000, do you know how to calculate x?

Take the log of 100000 which is 5, therefore x=5

So, if you have 6 = log x; can you therefore calculate x?

Take the antilog of 6 which is 1000000, therefore x=1000000
