Final answer:

To simplify a square root to decimal form, ensure an even power of 10 for exponentials, extract the root of perfect squares, use calculator functions appropriately, and apply estimation when precision isn't essential to provide the correct option in the final answer.

Step-by-step explanation:

To simplify a square root to decimal form, you might need to handle exponentials. If the number is in exponential form, such as 52 or 2.4 x 10-2, you start by making sure that the power of 10 is evenly divisible by 2. For a perfect square, you extract the square root of the digit term and divide the exponential term by 2.

When dealing with equations like (2x)2 = 4.0 (1 − x)2, you can take the square root of both sides since they are perfect squares. This process involves rearranging and solving for the unknown value. Additionally, when finding the square root of a perfect square fraction, first simplify it to its simplest form and then take the square root.

It's important to note that for calculations such as the fourth root or higher roots, you might need to use your calculator's specific functions like raising the number to the power of 0.25 for the fourth root or taking the square root twice in a row. Knowing how to use these functions on your calculator is essential for providing the correct option in the final answer.

Finally, you should give yourself a break when it comes to exact numbers, especially when the situation doesn't call for high precision. The concept of estimating can be useful when high precision isn't necessary, for example, estimating π as 3 for quick calculations related to circles.
