What is the definition of an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a * b^x, where a is a constant, b is a positive real number, and x is the exponent.

What is the base of a logarithm?

Back

The base of a logarithm is the number that is raised to a power to obtain a given value. For example, in log_b(a) = c, b is the base.

What is the relationship between exponential and logarithmic functions?

Back

Exponential functions and logarithmic functions are inverses of each other. If y = b^x, then x = log_b(y).

What is the product property of logarithms?

Back

The product property states that log_b(MN) = log_b(M) + log_b(N), where M and N are positive numbers.

Front

What is the quotient property of logarithms?

Back

The quotient property states that log_b(M/N) = log_b(M) - log_b(N), where M and N are positive numbers.

What is the power property of logarithms?

Back

The power property states that log_b(M^p) = p * log_b(M), where M is a positive number and p is any real number.

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.
