Final answer:
To find the value of x, we need more context from the question, but examples provided show methods like taking square roots or simplifying perfect squares. Without the complete equation, we cannot give a specific value for x.
Step-by-step explanation:
The question requires the value of x to be found from various mathematical expressions. Although the question itself is not clear, we can deduce certain methods to solve for x depending on the equations provided. For example, if we consider Eq. A.8. which can be interpreted as 5 to the square root because 5 multiplied by itself is 5, then we have x² = √x. This means that x can be expressed as a power of a fraction.
However, if we consider the equation from B, which was provided as x² (0.0150 - x)², it suggests that the equation is a perfect square and could potentially be simplified without using the quadratic formula.
One equation provided was (2x)² = 4.0 (1 - x)², which implies taking the square root on both sides could give (2x) (1 - x), leading to a simpler method to solve for x.
Without a complete question, it's challenging to provide a definitive answer, but these examples illustrate how to approach problems where you need to find the value of x.
