The logarithmic function is defined as For x 0 a 0 and a 1 y log a x if and only if x a y. Log b AC log b A log b C. Just take the logarithm of both sides of this equation and use equation 4 to conclude that.
You may have noticed that your calculator only has keys for figuring the values for the common that is the base-10 log and the natural that is the base-e logThere are no keys for any other bases.
