Removing Square Roots is a crucial strategy for solving equations involving square roots on the Digital SAT Math Section. When you encounter an equation with a square root, the key is to isolate the square root on one side of the equation and then square both sides. This effectively eliminates the square root, allowing you to solve the equation using standard algebraic techniques.Here’s an example to illustrate this strategy:Question: Solve for x: √(x + 3) = 5

Step 1: Isolate the square root (it’s already isolated in this case)
√(x + 3) = 5

Step 2: Square both sides of the equation
(√(x + 3))² = 5²

Step 3: Simplify
x + 3 = 25

Step 4: Solve for x
x = 22By squaring both sides, we removed the square root and transformed the equation into a simpler linear equation. This technique is especially useful when dealing with more complex equations involving square roots, as it allows you to simplify the problem and apply familiar algebraic methods. Remember to always check your solution by plugging it back into the original equation, as squaring can sometimes introduce extraneous solutions.
