Is it -3? Does log base 15 of nothing equal 0? And since 3,375 can be written in log base form as log base 15 of 3,375 equals 3, can you subtract 0-3 and get negative 3? Could I do it another way by just dividing the two logs since they have the same base so it'd be log base 15 ( 1/3,375) and if you write that in exponential form you should get negative 3? Or is the answer to this question no solution. Explain please! Thanks!  </SPAN>\n" );
