Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
1 + log3(5) is equivalent to 1 + log(5)/log(3)

you can use your calculator to see that the result is 2.464973521

the major concept used was:

loga(x) = logb(x)/logb(a)

this translates to log(x) to the base of a is equal to log(x) to the base of b divided by log(a)to the base of b.

that's the log base conversion formula that is widely used to convert any non-standard log base that can't be solved by the calculator to a base that can be used by the calculator.

those bases are the base of 10 which is the LOG function of the calculator, and the base of e which is the LN function of the calculator.

you can convert to either one and get the same answer.

example:

1 + log3(5) = 1 + log(5)/log(3) = 2.464973521

1 + log3(5) = 1 + ln(5)/ln(3) = 2.464973521
