Improper integral (between limits): negative 1/5 power: .

This integral is improper because the integrand increases without limit for values of x close to a value which is in the range of the integration. Consequently, we need to consider sum of the limits of the related integrals

If we express this as a power in the numerator, we can use the Power Rule of integration and get

, or

Substituting the limits of integration (but not yet evaluating the limit), we get

The limits of the (a - 1) and (b - 1) factors are 0, so

Similar problem which diverges.
