AI Thread Summary
A student from Ladoke Akintola University of Technology seeks clarification on a logarithmic expression, specifically "log^18 - log^10 = 19." There is confusion regarding the notation "log^18," questioning whether it represents log(18) and whether it refers to common log (base 10) or natural log (base e). The discussion suggests that if the problem is to find base 'a' such that loga(18) - loga(10) = 19, it can be simplified to loga(9/5). Ultimately, the goal is to determine the base 'a' that satisfies the equation a^19 = 9/5.

I don't see a question here! What is the question?

Also what does "log^18" mean? I that just log(18)? And is that common log (base 10) or natural log (base e)? Or is the problem to find base a such that loga(18)- loga(10)= 19?

If that is the case, you can simplify by using the fact that loga(18)- loga(10)= loga(18/10)= loga(9/5) and then you are trying to find a such that a19= 9/5.

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
