no transformations needed though just use the laws of Logarithms or whatever they're called. logarithms of number with exponents is just the exponent times the logarithms of the base or ln(a^x)=xln(a) then Logarithms of similar bases ln(e)=1 log(10)=1 log base 2 (2)=1
Where is the log came from? And why ln is called natural log? Who invented or who is the mathematicians that named the functions as log? When it was introduced in mathematics and its first applications?
