Converting Logarithms to Exponential Form

Front

What is the definition of a logarithm?

Back

A logarithm is the power to which a number (the base) must be raised to obtain another number. For example, in the equation log_b(a) = c, b^c = a.

What is the base in a logarithmic expression?

Back

The base in a logarithmic expression is the number that is raised to a power. In log_b(a), b is the base.

Front

What is the relationship between logarithms and exponents?

Back

Logarithms are the inverse operations of exponentiation. If b^c = a, then log_b(a) = c.
