you want to have (-50/9)(5x-3)^(-5/3) = 0
then (5x-3)^(-5/3) = 0
or
1/(5x-3)^(5/3) = 0
Clearly this has no solution.
Think of it this way:
1 divided by what number would give you zero?? There is no such number
So since your equation has no solution, there is no point of inflection.
26. Find all points of inflection.
f(x) = (5x-3)^(1/3)
Note: I have gotten
f''(x) = (-50/9)(5x-3)^(-5/3)
I would like to know how to figure out the zeros.
