Question

which of the following is not a perfect square (a) 841

Answer 1

Hey !!

yeah The Given Number 841 Is A perfect square .

Answer 2

ANSWER..............,

841 is a perfect square because the square root of 841 is 29(i.e 29*29=841)

529 is a perfect square also because the square root is 23(i.e 23*23=529)

But,198 is not a perfect square because it's square root is 14.071. We know that, a number ending with digits 2, 3, 7 or 8 can never be a perfect square.

So, 198 cannot be written in the form of a perfect square.
