Frequently Asked Questions

What are the three logarithm expansion properties?

Product property: log_n(a*b) = log_n(a) + log_n(b). Quotient property: log_n(a/b) = log_n(a) - log_n(b). Power property: log_n(a^k) = k * log_n(a).

Why expand a logarithm instead of just evaluating it directly?

Expanding breaks a complicated log expression into simpler pieces that are each easier to evaluate, simplify algebraically, or combine with other terms in a larger equation.

How is this different from the condense logarithms calculator?

This calculator does the reverse: starting from one combined logarithm expression and breaking it into separate simpler terms. The condense calculator instead starts with separate terms and combines them into one.
