Question

Find the least number which must be added to each of the following numbers to get a perfect square. Also, find the square root of the perfect square so obtained. i. 425 ii. 8400 iii. 4515600​

Answer 1

Step-by-step explanation:

I.So,16 will be added to 425 to get a perfect square

$\sqrt{441} = 21$

II.So,64 will be added to the 8400 to get a perfect square

sqrt(8464)=92

III.4515600+25=4515625

So, 25 will be added to the 4515600 to get a perfect square.

sqrt(4515625)=2125
