How can I develop the function below ? Where should I start to read?
"""
HSLOG = "High School Log".
Treat forms like `\log_b(a^p)` in a special manner.
Standard sage log with integer arguments works like this:
::
sage: log(101^3,10)
log(1030301)/log(10)
sage: 3*log(101,10)
3*log(101,10)
sage: 10^log(101,base=10) #101
10^(log(101)/log(10))
and
::
sage: log(101,10)
log(101)/log(10)
sage: latex( log(101,10) )
\frac{\log\left(101\right)}{\log\left(10\right)} %ie: log(101)/log(10)
What we want is:
sage: HSLOG(101,10,3) #log_{10}(101^3)
3*log(101,10)
sage: HSLOG(101,10) #log_{10}(101)
log(101,10)
sage: 10^HSLOG(101,10) #10^log_{10}(101^3) = 101
101
sage: latex( HSLOG(101,10) )
\log_{10}(101)
