What does a negative exponent mean?

A negative exponent represents the reciprocal of the positive exponent version — for example, 2 to the power of -3 equals 1 divided by 2 to the power of 3, or 1/8.

What does a fractional exponent mean?

A fractional exponent represents a root — for example, raising a number to the power of 1/2 is the same as taking its square root, and to the power of 1/3 is the same as taking its cube root.

How are logarithms and exponents related?

They're inverse operations — if a base raised to an exponent equals a value, then the logarithm (in that same base) of that value equals the exponent. Each one undoes the other.

Can I calculate a logarithm in an unusual base, like base 5?

Yes — this calculator works for any positive base, not just the common base 10 or base e (natural log), so you can compute a logarithm in whatever base your problem requires.
