Final answer:

Solving equations may require rounding to the nearest hundredth place, considering real-life context, and attention to significant figures. The specific solution process depends on the accurate and correctly formatted equation.

Step-by-step explanation:

We want to solve the equation presented by the student, but there seems to be a typo in the original question. However, based on the context provided, we can infer a few potential methods for solving equations that result in numerical solutions which can then be rounded to the hundredth place.

When rounding to the hundredth place:

  • If a calculator gives an answer like 201.867, you would round to 201.87 because the next digit (7) is 5 or higher.
  • When the equation involves roots, and you get x = 0.0216 or x = -0.0224, it's clear that these represent two potential solutions to a quadratic equation.
  • In context with real-life application where negative results may not make sense, such as in measurements, one would only consider the positive solution, e.g., x = 0.00139.
  • Furthermore, in equations involving significant figures, it's crucial to round the answer to match the precision of the given data, such as reporting an answer of 922.00 when rounded with significant figures.

Due to the lack of a clear equation in this question, we cannot provide a specific solution to this problem. It's essential to ensure that the equation is accurate and correctly formatted before attempting to solve and round the solution to the nearest hundredth.
