<output>84</output>
84   That's pretty close to 80 already so I can cancel D and E since they'll be more than 80. B just needs to be checked just in case so...   3^3 + 5*3= 27 + 15 = not close to 80.   Therefore, 4 (4) is the smallest positive integer x for which x^3 + 5x has a value more than 80.ANSWER:4
