1. The problem is to verify if the answer is 49 for the given question (not explicitly stated). 2. Since the user states the answer might be 49, let's consider a common algebraic problem where 49 could be the answer, such as solving $x^2 = 49$. 3. The formula to solve this is $x = \pm \sqrt{49}$. 4. Calculate the square root: $\sqrt{49} = 7$. 5. Therefore, the solutions are $x = 7$ or $x = -7$. 6. If the problem was to find $x^2$ given $x=7$, then $7^2 = 49$. 7. Hence, 49 is a valid answer for problems involving squares of 7 or solutions to $x^2=49$.
