To compare \(\sqrt{81}\) and \(\sqrt{88}\), we first calculate their square roots:
\(\sqrt{81} = 9\)
Next, we approximate \(\sqrt{88}\). We know that:
\(\sqrt{88} \approx 9.38\) (since \(9^2 = 81\) and \(10^2 = 100\), \(\sqrt{88}\) is between 9 and 10)
Now, we can compare:
\[ 9 < 9.38 \]
Thus, the inequality statement comparing \(\sqrt{81}\) and \(\sqrt{88}\) is:
\(\sqrt{81} < \sqrt{88}\)
So, the answer is:
\(\sqrt{81} < \sqrt{88}\)
