If you could explain to me how logs work that'd be great! Thank you. .. One definition of a logarithm I find most useful is this: The base raised to the logarithm of a number=number. This is called the exponential form of a logarithm. In your case, the base=12, the number is 1/144 and you are trying to find the logarithm of 1/144. In other words, what do you raise 12, to equal 1/144. 12^x=1/144 1/144=1/12^2=12^-2 12^x=12^-2 since the bases are equal, the exponents must be equal to each other, that is, x=-2, the logarithm of 1/144, base 12. To check: raise 12 to -2=12^-2=1/12^2=1/144
