If log 6=.7781 then what is log 60,000

By using the calculator, log 6 = 0.7781 ...

log 60,000 is just equal to log (6 * 10,000)

log (6 * 10,000) = log 6 + log 10,000

As we know that log 10 = 1, log 100 = 2, log 1000 = 3, and so on.

So log 10,000 = 4

Going back to our equation,

log (6 * 10,000) = log 6 + log 10,000

log 60,000 = 0.7781 + 4

So log 60,000 = 4.7781
