Expand the logarithmic expression - Warning: Just as when you're dealing with exponents, the above rules work only if the bases are the same. For instance, the expression "log d (m) + log b (n)" cannot be simplified, because the bases (the d and the b) are not the same, just as x 2 × y 3 cannot be simplified because the bases (the x and y) are not the same.
