Step-by-step explanation:

Step 1: Define

x² = 625

Step 2: Solve for x

Square root both sides: x = ±25

Step 3: Check

Plug in x into the original equation to verify it's a solution.

x = -25

Substitute in x: (-25)² = 625
Exponents: 625 = 625

Here we see that 625 does indeed equal 625.

∴ x = -25 is a solution to the equation.

x = 25

Substitute in x: 25² = 625
Exponents: 625 = 625

Here we see that 625 does indeed equal 625.

∴ x = 25 is a solution to the equation.
