दिया गया है:

संख्या = 6659

प्रयुक्त सूत्र:

इसे पूर्ण वर्ग बनाने के लिए जोड़ी जाने वाली सबसे छोटी संख्या ज्ञात करने के लिए।

गणनाएँ:

6659 से कम निकटतम पूर्ण वर्ग 812 = 6561 है। 

⇒ अंतर = 6659 - 6561 = 98

6659 से अधिक निकटतम पूर्ण वर्ग 822 = 6724 है

⇒ अंतर = 6724 - 6659 = 65

∴ सही उत्तर विकल्प 2 है।
