Provide an appropriate response.A student claims that since logbx = a is not defined for negative values of x, then a must also not be negative. What is wrong with this statement?
What will be an ideal response?
a is an exponent, and if a positive b is raised to a negative power the result will be positive. So, it is possible that a be negative when x is positive.
