1. Let's first clarify the problem: "It’s have to be 49." If this means we need to find a number or expression that equals 49, we can start by considering simple squares since 49 is a perfect square. 2. Recall that 49 equals $7^2$. This means any expression that evaluates to $7 \times 7$ equals 49. 3. If you meant to solve for $x$ in $x = 49$, the answer would plainly be $x = 49$. 4. If you want to find $x$ such that $x^2 = 49$, then solving the equation: $$x^2 = 49$$ Take the square root of both sides: $$x = \pm \sqrt{49}$$ $$x = \pm 7$$ 5. So, the two values for $x$ that satisfy $x^2 = 49$ are $7$ and $-7$. If this is not what you intended, please clarify your question further.
