Identify the number that does not belong with the other three. Explain your reasoning.
mojhsa [17]

Answer:

To identify which integer does not belong with the rest, we must first evaluate each.

Step-by-step explanation:

  • [25.6...] is already evaluated. Therefore, let's move on to Integer <em>b: </em>\sqrt{x}, where is <em>x </em>is 48.

  • 48 = 2 * 24--> 2 * 12--> 2 * 6--> 2 * 3
  • √48 = \sqrt{2} * 2 * 2 * 2 * 3
  • We have 1 perfect sqaure: \sqrt{2} * 2
  • When we multiply, we receive 2.
  • Therefore, 2 * \sqrt{2 * 3}

  • When -51/2 is relatively prime, we receive -25 1/2

  • Finally, the last integer is already simplified.

Based on these results, you may determine the number that does not belong with the other three, whether than is through means of irrationability, value, absolte value, or whatever other means you decide.
