Math Problem Statement

The positive square root of 262 lies between which two consecutive positive integers 18 and 19 14 and 15 15 and 16 16 and 17 17 and 18

Solution

To determine between which two consecutive positive integers the positive square root of 262 lies, we need to find the approximate value of 262\sqrt{262}.

First, let's find the squares of the given integer pairs:

  • 142=19614^2 = 196
  • 152=22515^2 = 225
  • 162=25616^2 = 256
  • 172=28917^2 = 289
  • 182=32418^2 = 324
  • 192=36119^2 = 361

Now, let's analyze:

  • 162=25616^2 = 256 is less than 262.
  • 172=28917^2 = 289 is greater than 262.

Since 256<262<289256 < 262 < 289, the square root of 262 lies between 16 and 17.

Answer: The positive square root of 262 lies between the consecutive positive integers 16 and 17.
