Answer 1

In a common log we have an unwritten base of 10.  That is, filling in our equation correctly, we have $7.5= log_{10} x$.  Logs and exponential functions are opposites of one another, so we can rewrite that log as an exponential function, like this: $10 ^{7.5} =x$.  Doing that math on our calculators we get that x is 31622776.60
