Simplifications of logarithmic expressions are based on the properties of logarithms
log(1)=0
log(a/b)=log(a)-log(b)
log(a^n)=n*log(a)
log_b(x)=log(x)/log(b)=ln(x)/ln(b)
As to exponentials you have
e^(0)=1
e^(-a)=1/(e^a)
(e^a)*(e^b)=e^(a+b)
(e^a)^n=e^(na)
That is the gist of it.
But I do not think that your calculator is able to handle any scientific calculations.
1) Multiplication inside the log can be turned into addition outside the log, and vice versa.
2) Division inside the log can be turned into subtraction outside the log, and vice versa.
3) An exponent on everything inside a log can be moved out front as a multiplier, and vice versa.
