Final answer:
To solve for w, square both sides of the equation √w to eliminate the square root symbol and find the value of w that satisfies the given equation.
Step-by-step explanation:
To solve for w in the equation √w, we need to square both sides of the equation to eliminate the square root symbol. This gives us w = (√w)² = w. So, any value of w that satisfies the equation √w = w + 78 = 98 is a solution.
