Question

वह छोटी से छोटी संख्या ज्ञात कीजिये जिसे 4931 में जोड़ दे तो योगफल पूर्ण वर्ग हो जाये

Answer 1

as we know square of 70 = 4900

but 4931 is greater than 4900 and we have to add to 4931

So, we have to take square of 71 = (71)² = 5041

we need to add = 5041 - 4931 = 110

We need to add 110 to 4931 to make it a perfect square
