Answer 1

To evaluate the statements, we can find the square roots of the numbers involved:

1. **\(\sqrt{49}\)**:
- This is equal to 7.

2. **\(\sqrt{48}\)**:
- The approximate value of \(\sqrt{48}\) is around 6.93 since \(\sqrt{48} \approx 6.928\).

3. **\(\sqrt{36}\)**:
- This is equal to 6.

Now, let's evaluate each statement:

1. **\(\sqrt{49} > 7\)**:
- This is false, as \(\sqrt{49} = 7\).

2. **\(\sqrt{49} < 7\)**:
- This is also false, as \(\sqrt{49} = 7\).

3. **\(\sqrt{48} > \sqrt{36}\)**:
- Since \(\sqrt{48} \approx 6.928\) and \(\sqrt{36} = 6\), this is true.

4. **\(\sqrt{48} < \sqrt{36}\)**:
- This is false because, as established, \(\sqrt{48} \approx 6.928\) which is greater than 6.

Therefore, the true statement is:
\[
\sqrt{48} > \sqrt{36}
\]
