To solve the equation \(\frac{\sqrt{x}}{\sqrt{x} - 1} - \frac{1}{x - \sqrt{x}} : \sqrt{x} + \frac{1}{\sqrt{x} + 2} = 2\), let's break it down step by step.

First, let's simplify the left-hand side of the equation:

1. **Simplify the expression inside the division:**

\[
\frac{\sqrt{x}}{\sqrt{x} - 1} - \frac{1}{x - \sqrt{x}}
\]

To combine these fractions, we need a common denominator. The common denominator is \((\sqrt{x} - 1)(x - \sqrt{x})\).

\[
\frac{\sqrt{x}(x - \sqrt{x}) - 1(\sqrt{x} - 1)}{(\sqrt{x} - 1)(x - \sqrt{x})}
\]

Simplify the numerator:

\[
\sqrt{x}(x - \sqrt{x}) - (\sqrt{x} - 1)
\]

Distribute \(\sqrt{x}\):

\[
\sqrt{x} \cdot x - \sqrt{x} \cdot \sqrt{x} - \sqrt{x} + 1
\]

Simplify further:

\[
x\sqrt{x} - x - \sqrt{x} + 1
\]

2. **Simplify the entire left-hand side expression:**

Now we need to divide this by \(\sqrt{x} + \frac{1}{\sqrt{x} + 2}\):

\[
\frac{x\sqrt{x} - x - \sqrt{x} + 1}{(\sqrt{x} - 1)(x - \sqrt{x})} : \left( \sqrt{x} + \frac{1}{\sqrt{x} + 2} \right)
\]

This is equivalent to multiplying by the reciprocal:

\[
\frac{x\sqrt{x} - x - \sqrt{x} + 1}{(\sqrt{x} - 1)(x - \sqrt{x})} \cdot \frac{1}{\sqrt{x} + \frac{1}{\sqrt{x} + 2}}
\]

Simplify the denominator of the second fraction:

\[
\sqrt{x} + \frac{1}{\sqrt{x} + 2} = \frac{(\sqrt{x}(\sqrt{x} + 2) + 1)}{\sqrt{x} + 2}
\]

Simplify further:

\[
\frac{x + 2\sqrt{x} + 1}{\sqrt{x} + 2}
\]

Now the expression becomes:

\[
\frac{x\sqrt{x} - x - \sqrt{x} + 1}{(\sqrt{x} - 1)(x - \sqrt{x})} \cdot \frac{\sqrt{x} + 2}{x + 2\sqrt{x} + 1}
\]

3. **Set the simplified expression equal to 2:**

\[
\frac{(x\sqrt{x} - x - \sqrt{x} + 1)(\sqrt{x} + 2)}{(\sqrt{x} - 1)(x - \sqrt{x})(x + 2\sqrt{x} + 1)} = 2
\]

4. **Solve for \(x\):**

This is a complex rational equation. To solve it, you would typically clear the fractions by multiplying both sides by the common denominator and then solve the resulting polynomial equation. However, given the complexity, it might be easier to use numerical methods or graphing to find the solution.

Given the complexity of the algebra involved, it might be more practical to use a numerical solver or graphing calculator to find the value of \(x\) that satisfies the equation.
