To analyze the statements, we need to calculate the values of the square roots:

  1. √48 > √36:

    • √36 = 6
    • To compare √48 to 6, we can approximate √48. We know that √49 = 7 (since 49 is a perfect square) and √36 = 6. Therefore, √48 is between 6 and 7, but closer to 7.
    • Since √48 is not clearly greater than zero, we check: 48 < 49 (but greater than 36). Thus, we cannot definitively claim √48 > √36.
  2. √48 < √36:

    • As established before, √36 = 6, and √48 is greater than √36, since 48 is greater than 36. So, this statement is false.
  3. √49 > 7:

    • √49 = 7. Therefore, this statement is false.
  4. √49 < 7:

    • Again, since √49 = 7, this statement is false.

Thus, the true statement among the given options is: √48 > √36.
