Answer 1

hey guess.

which question your problem?

Answer 2

Answer:

ans 8 Well, 306455 is less than 1000 times 1000, so the square root is probably about 500.

306455500=612.91

Well, that’s too high, so we can guess somewhere between 306455613,500

(306455613+500)2≈556

306455556.5=551

So we know it’s between 551 and 556 somewhere!

5522=303601

5532=305809

5542=306916

554^2 is the first perfect square greater than 306445, so we need to add:

"Something"+305445=5542

 =>   306445-5542

=> 471

ans 9 91^2 = 8281 is less then 8400

92^2 = 8464 is greater then 8400

so, 92^2-91^2  

=8464 - 8400

= 64 is the least number.

ans 10 32^2 is more than 1000 by 24; So the least number to be added to 1000 is 24. Therefore, 1000+24 = 1024 is the smallest four digit number which is a perfect square.

ans 11 So here we can see that 99999 is not a perfect square as it leaves 143 as the remainder while finding it s square root. Hence 99856 is a perfect square whose square root is √99856 = 316.
