Improper integral
Just got an odd result for the improper integral evaluated from 0 to 33 of 1/(5th root of x-1). It should evaluate to 75/4 or 18.75. In home, I get 18.7479519638 after a busy spell hourglass. In CAS, I get a choice of 155/4 (way off!) or 18.750007847.

The HP 39gii after awhile has ER: Invalid Input.

The TI NSpire immediately produces 75/4.
