81−−√>9

Answer 1

To evaluate which statement is true, let's analyze each one:

1. **\(\sqrt{81} < 9\)**
\(\sqrt{81} = 9\)
This statement is false.

2. **\(\sqrt{71} > \sqrt{61}\)**
Since 71 > 61, then \(\sqrt{71} > \sqrt{61}\).
This statement is true.

3. **\(\sqrt{71} < \sqrt{61}\)**
This statement is false, as already determined in the previous step.

4. **\(\sqrt{81} > 9\)**
Again, \(\sqrt{81} = 9\).
This statement is false.

Therefore, the true statement is **\(\sqrt{71} > \sqrt{61}\)**.
