The given equation is:

$\left\lfloor \sqrt{n} + \sqrt{n+1} + \sqrt{n+2} \right\rfloor = \left\lfloor \sqrt{9n + 8} \right\rfloor$

Where $\lfloor x \rfloor$ represents the floor function, which gives the greatest integer less than or equal to $x$.

To solve this equation, we need to explore the possible integer values of $n$ such that the floor values of both sides are equal.

Steps:

1. Analyze the behavior of both sides:

   • The left side involves three square roots added together.
   • The right side simplifies to a single square root function of $n$.

2. Approximate small values of $n$: We will try integer values of $n$ to see when the equation holds.

Let's start solving this through approximations:

For $n = 0$:

$\left\lfloor \sqrt{0} + \sqrt{1} + \sqrt{2} \right\rfloor = \left\lfloor 0 + 1 + 1.414 \right\rfloor = \left\lfloor 2.414 \right\rfloor = 2$ $\left\lfloor \sqrt{9(0) + 8} \right\rfloor = \left\lfloor \sqrt{8} \right\rfloor = \left\lfloor 2.828 \right\rfloor = 2$ Thus, $n = 0$ is a solution.

For $n = 1$:

$\left\lfloor \sqrt{1} + \sqrt{2} + \sqrt{3} \right\rfloor = \left\lfloor 1 + 1.414 + 1.732 \right\rfloor = \left\lfloor 4.146 \right\rfloor = 4$ $\left\lfloor \sqrt{9(1) + 8} \right\rfloor = \left\lfloor \sqrt{17} \right\rfloor = \left\lfloor 4.123 \right\rfloor = 4$ Thus, $n = 1$ is also a solution.

For $n = 2$:

$\left\lfloor \sqrt{2} + \sqrt{3} + \sqrt{4} \right\rfloor = \left\lfloor 1.414 + 1.732 + 2 \right\rfloor = \left\lfloor 5.146 \right\rfloor = 5$ $\left\lfloor \sqrt{9(2) + 8} \right\rfloor = \left\lfloor \sqrt{26} \right\rfloor = \left\lfloor 5.099 \right\rfloor = 5$ Thus, $n = 2$ is another solution.

Conclusion:

The values of $n = 0, 1, 2$ satisfy the equation. Therefore, these are the solutions to the equation.

Let me know if you'd like further clarification, and here are 5 related questions to explore:

1. How does the floor function affect the solution process?
2. Why is it important to test small values of $n$ first in equations like this?
3. Can this equation have solutions for larger values of $n$?
4. What methods can be used to approximate the values of square roots without a calculator?
5. How does the presence of square roots in the equation impact the behavior of the functions?

Tip: When dealing with floor functions and square roots, always check boundary values carefully to ensure accuracy in approximations.
