Q. Which two integers is 62–\sqrt{62} between?\newlineChoices:\newline(A)9–9 and 8–8\newline(B)8–8 and 7–7\newline(C)6–6 and 5–5\newline(D)10–10 and 9–9
  1. Identify Perfect Squares: Identify the perfect squares near 6262. The perfect square just below 6262 is 4949. The perfect square just above 6262 is 6464.
  2. Calculate Square Roots: Calculate the square roots of 4949 and 6464.49=7\sqrt{49} = 764=8\sqrt{64} = 8
  3. Determine Negative Square Roots: Determine the negative square roots.\newline49=7-\sqrt{49} = -7\newline64=8-\sqrt{64} = -8
  4. Place Negative Square Roots: Place 62-\sqrt{62} in relation to 7-7 and 8-8. Since -8 < -\sqrt{62} < -7, 62-\sqrt{62} is between 8-8 and 7-7.
