2 8 = 3, which is defined as the ''logarithm form''. It must be clear to you that the same statement is written in index form and in logarithm form. Accordingly, since 23 = 8, we also have log 2 8 = 3. Similarly, log 2 8 = 3, means 23 = 8. Let us consider several other examples. • Since 32 = 9, the logarithm of 9 to base 3 is 2. That is, log
