To solve the equation \(x^2 = 7^8\) by inspection, we can take the square root of both sides.
Taking the square root gives us:
\[ x = \pm 7^4 \]
Calculating \(7^4\):
\[ 7^4 = (7^2)^2 = 49^2 = 2401 \]
Thus, the two real solutions are:
\[ x = -7^4 \quad \text{and} \quad x = 7^4 \]
So the lesser number first is:
\[ -7^4 \quad \text{and} \quad 7^4 \]
In exponent form, the solutions are:
\[ -7^4 \quad \text{and} \quad 7^4 \]
