தர்க்கம் : முதல் எண் = (இரண்டாம் எண்ணின் வர்கம் + 1)

அதனால்,

  • 19 : 324

19 = \( \sqrt{324}\) + 1

19 = 18 + 1

19 = 19 (LHS = RHS)

மற்றும்,

  • 25 : 576

25 = \( \sqrt{576}\) + 1

25 = 24 + 1

25 = 25 (LHS = RHS)

இதேபோல்,

  • 9 : ?

9 = \( \sqrt{x}\) + 1

9 - 1 = \( \sqrt{x}\)

8 = \( \sqrt{x}\)

\(x\) = \({8^2}\)

\(x\) = 64

எனவே, "64" என்பது சரியான பதில்.
