Converting Logarithms to Exponential Form

Front

What is the definition of a logarithm?

Back

A logarithm is the exponent to which a base must be raised to produce a given number. It is expressed as log_b(a) = c, which means b^c = a.

What is the base in a logarithmic expression?

Back

The base in a logarithmic expression log_b(a) is the number b that is raised to the power of c to obtain a.

What is the relationship between logarithms and exponents?

Back

Logarithms and exponents are inverse operations. If b^c = a, then log_b(a) = c.

What is the change of base formula for logarithms?

Back

The change of base formula states that log_b(a) = log_k(a) / log_k(b) for any positive k.

What is the product rule for logarithms?

Back

The product rule states that log_b(xy) = log_b(x) + log_b(y) for any positive x and y.

What is the quotient rule for logarithms?

Back

The quotient rule states that log_b(x/y) = log_b(x) - log_b(y) for any positive x and y.
