Answer 1

Answer:

1 I not understand u r question

Answer 2

Answer:

Estimation makes one's life easier.

Ignore unit's digit because that's what we are looking for. Ignore the tens digit. Consider the rest.

441. Its root is 21.

So least perfect square using 21 at tens digit is

210^2=44100

Next higher is 211^2=44521

So we need to add 358(44521–44163).

This is least no. We can add anything to make perfect square of next higher no 212, 213,214…
