Oh dear. Why bother to go through all the math (such as there is) and then suddenly go and use the actual values of log 5 and log 3 ? May as well get your calculator our right away....
@@pjaj43 calculators do it all for you now. You can put any base in. Gone are the days of only have log base 10 and natural log tables! Oh but I did love them.
@@pjaj43 myscript calculator on the ipad you hand write log3 45. The three must be a little subscript. I’ve been using it for so long I didn’t realise normal calculators don’t do it 😂 However you can convert a log base 10, by using log base 10 of the number divided by log base 10 of the base you want. Eg log 100 = 2. But log base 2 of 100 = log 100/ log 2 . = 2/ 0.301..= 6.64…. Lovely neat trick. Log rules; love them!
