1. We need to find all real numbers $$ x $$ such that
   $$
   x^2 = 49.
   $$

2. Taking the square root of both sides, we consider:
   $$
   x = \sqrt{49} \quad \text{or} \quad x = -\sqrt{49}.
   $$

3. Since $$\sqrt{49} = 7$$, the solutions are:
   $$
   x = 7 \quad \text{or} \quad x = -7.
   $$

4. Therefore, the real square roots of 49 are:
   $$
   7, -7.
   $$
The real square roots of 49 are 7 and -7.
