Exponential to Logarithmic

Front

What is the relationship between exponential and logarithmic functions?

Back

Exponential functions can be expressed in terms of logarithmic functions, and vice versa. If a^b = c, then log_a(c) = b.

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. For example, log_b(a) = c means b^c = a.

What is the change of base formula for logarithms?

Back

The change of base formula states that log_a(b) = log_c(b) / log_c(a) for any positive c.

What is the value of log_10(1000)?

Back

log_10(1000) = 3, because 10^3 = 1000.

Front

What is the value of log_2(8)?

Back

log_2(8) = 3, because 2^3 = 8.
