1. Problem Description

We need to find two consecutive integers aa and bb such that a<111<ba < \sqrt{111} < b.

2. Solution Steps

We are looking for perfect squares close to
1
1

1. We know that $10^2 = 100$ and $11^2 = 121$.

Since 100<111<121100 < 111 < 121, we have 100<111<121\sqrt{100} < \sqrt{111} < \sqrt{121}.
This means 10<111<1110 < \sqrt{111} < 11.
Thus, the two consecutive integers are 10 and
1
1.

3. Final Answer

10<111<1110 < \sqrt{111} < 11
