Question

Find the least number which must be subtracted from 7956 to obtain a perfect square. Find thi
perfect square and its square root.​

Answer 1

Answer:

900               ( least number )

8,10,000       ( perfect square )

30                  ( square root )

Step-by-step explanation:

To attain the least number by subtracting 7956 to obtain a perfect square will be ,

7956 - ( 84 )²   ( Because subtraction from 7956 from  perfect squares of 80 to 89 does not yield a perfect square except 84 )

( 84 )² = 7056

Therefore ,

7959 - 7056

= 900

Therefore 900 will be the least number which must be subtracted from 7956 to obtain a perfect square.

Finding perfect square of 900 :

= 900 x 900

= 8,10,000

Finding perfect square root of 900 :

√900

= 30

The perfect square will be 8,10,000 and the perfect square root will be 30 .
