Final answer:
The question is unclear and lacks the necessary information to provide a simplification. A complete mathematical expression is needed to offer the correct step-by-step simplification process.
Step-by-step explanation:
The question provided seems to have some errors or missing parts, making it unclear which mathematical operation is being asked for simplification. Without further context, it is challenging to determine how to simplify the expression '68√'. If we are to consider possible operations or expressions that could be related to the given snippet, this could involve simplifying a square root, a rational expression, or something else entirely. Nevertheless, it is essential to have a clear and complete mathematical expression to provide a correct simplification. I would advise the student to review the question and ensure that all necessary information is provided, including any operations or expressions that need simplification.
