From an intermediate algebra class example:

How would this be implemented in the hp prime?

Hi.

Pretty sure it's not the best way, but I did it like this:

Code:

#cas

combineLog(expr1,resBase):=

BEGIN

LOCAL res;

expr1:=lncollect(expr1);

res:=solve(expr("expr1=logb(k,resBase)"),k);

RETURN(logb(res,resBase));

END;

#end

Just make sure CAS has "Use i" enabled.

Thanks, I didn't have "Use i" enabled.
