5.6.2 Converting between Exponential and Logarithmic Functions

Question 1

log function

Answer 1

• When converting from logarithmic form to exponential form, remember that “a log is an exponent.” This means that the
  number the log is equal to becomes the exponent in the new form. The base of the log is the base of the exponent too.
  • A log written without a “b” value is the common log.
  y = logx
  In a common log, the “b” value is understood to be 10. In other words, y = logx is equivalent to the statement 10^y=x
