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
