Provide an appropriate response.A student argues that the best choice for the logarithmic base to be used in solving 8x = 76 is 8. What is wrong with this thinking?
What will be an ideal response?
The only logarithmic keys on a calculator are those used for obtaining base 10 and base e logarithms. To use base 8 would make evaluating log876 more difficult.
