It is not clear to me above what is the base of the log. Unstated, we often use base 10, but not always. I am not certain what you are doing. But the point of the above is something else..
log Y + log x= log (x*Y)
so log(5*1.5*10^9)=9log(7.5)
In my textbook, there's an equation with log
ex.
log(50,000)+log(150,000)= some number
But when I use the log button on the calculator, the answer is not correct? But when I use the ln button, it's the correct answer?
So for log, you press ln, then what is the log button on the calculator for?

the equation in my book is
0.5log(50,000)+0.5log(150,000)=11.37
I just punch these numbers and using log button on my calculator, the answer isn't correct. But when i use ln instead of log on my calculator, the answer is correct.
0.5log(50,000)+0.5log(150,000)=11.37
