To solve the equation x^2=400, we need to take the square root of both sides of the equation. However, it's important to remember that the square root of a number can have a positive and negative solution.
First, starting with x^2=400, we take the square root of both sides:
√(x^2) = ±√400
This simplifies to:
x = ±20
So, "step 1" in solving x^2=400 is to find the square root of 400 which gives us two solutions: x = 20 and x = -20.
