Exponent and Log Form

• True, subtraction between two logarithms is division in condensed form.

• True, a logarithm is an exponent. When dividing like bases you subtract exponents therefor dividing logarithms as in this example.

• False, subtraction between two logarithms is division within a single logarithm in condensed form.

A logarithm is always represents

• an exponent.

• a base.

• an answer.

• a unicorn.
