The image you uploaded contains a mathematical equation that has been worked on. Let's go through the steps shown in the image to solve the equation:

1. The equation starts with: $2^{x+2} = \sqrt{2}$

2. The square root of 2 can be rewritten as a power of 2: $\sqrt{2} = 2^{\frac{1}{2}}$ So, the equation becomes: $2^{x+2} = 2^{\frac{1}{2}}$

3. Since the bases on both sides of the equation are the same (both are base 2), we can set the exponents equal to each other: $x + 2 = \frac{1}{2}$

4. To solve for $x$, subtract 2 from both sides: $x = \frac{1}{2} - 2$

5. Simplify the right-hand side: $x = \frac{1}{2} - \frac{4}{2} = \frac{-3}{2}$ Thus, $x = -\frac{3}{2}$.

So, the solution to the equation is $x = -\frac{3}{2}$.
