Problem: find the smallest number which should be multiplied with 520 to make it a perfect square
Rationale: "explanation : 520 = 26 * 20 = 2 * 13 * 22 * 5 = 23 * 13 * 5 required smallest number = 2 * 13 * 5 = 130 130 is the smallest number which should be multiplied with 520 to make it a perfect square . answer : e"
annotated_formula: divide(divide(divide(divide(divide(520, const_3), const_3), const_4), const_4), const_4)
