How do you expand logarithms?

Like an algebraic expression, it is possible to expand logarithms, which is a way of “picking apart” an expression. The following lists two examples of expanding a logarithmic expression:

  • To expand log2(3x) = log2(3) + log2(x)
  • To expand log2(12/x) = log2(12) - log2(x)
