Find the least number which must be added to each of the following num

1.	Find the least number which must be added to each of the following numbers so as to get a perfect square. Also, find the square root of the perfect square so obtained.(1)6412
Answer» $\rule{300}2$ Your Answer: √6412= 80.07 So, the nearest SQUARE ROOT is 81 if we ADD something. Now, we know we have to obtain 81² by adding x in 6412 => 81² = 6412 + x => 6561 = 6412 + x => 6561 - 6412= x => 149 = x So, the number we have to add is 149 and the its square root is 81 Plz Mark it as brainliest. $\rule{300}2$

$\rule{300}2$

Your Answer:

√6412= 80.07

So, the nearest SQUARE ROOT is 81 if we ADD something.

Now, we know we have to obtain 81² by adding x in 6412

=> 81² = 6412 + x

=> 6561 = 6412 + x

=> 6561 - 6412= x

=> 149 = x

So, the number we have to add is 149 and the its square root is 81

Plz Mark it as brainliest.
