Answer 2

Answer:

461

Step-by-step explanation:

To Find: Find the least number which must be added to 306455 to obtain a perfect square.

Solution :

$\sqrt{306455} =553.58$

since the square root of given number is 553.58

so, the perfect square root will be 554

so, $554*554=306916$

Thus $\sqrt{306916}=554$

So, the least number which must be added to 306455 = 306916-306455

                                                                                           = 461

Hence,the least number which must be added to 306455 to obtain a perfect square is 461
