Solution set?
![The image contains the following mathematical equation and description:
\[2^{x-7} = 4\]
Below the equation, it says:
**solution set =**
The text next to the "solution set" appears to be an incomplete or scribbled portion, likely intended to represent where the solution would be placed.
To solve the equation \(2^{x-7} = 4\), consider the following steps:
1. Recognize that \(4\) can be expressed as a power of \(2\), specifically \(2^2\).
2. Set the exponents equal to each other since the bases are the same:
\[x - 7 = 2\]
3. Solve for \(x\):
\[x = 9\]
The solution set is \(\{9\}\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3fa757ec-9ef0-41e2-a2d2-ee98e8402c6d%2Fe6c11c23-48db-4fbd-998c-0e48e22e44a3%2Fchfpfyv_processed.jpeg&w=3840&q=75)
