Q. The value of 87 \sqrt{87} is between which two whole numbers?\newline88 and 99\newline99 and 1010\newline4343 and 4444\newline8181 and 100100
  1. Identify Perfect Squares: First, identify the perfect squares closest to 8787 to determine the possible whole number range. The perfect squares closest to 8787 are 8181 (929^2) and 100100 (10210^2).\newlineCalculation: 92=819^2 = 81, 102=10010^2 = 100
  2. Calculate Square Roots: Next, since 8787 is between 8181 and 100100, 87\sqrt{87} must be between 81\sqrt{81} and 100\sqrt{100}. Calculate the square roots of 8181 and 100100.\newlineCalculation: 81=9\sqrt{81} = 9, 100=10\sqrt{100} = 10
  3. Conclude Square Root Range: Conclude that 87\sqrt{87} is between 99 and 1010.\newlineCalculation: 9 < \sqrt{87} < 10
