Final answer:
The expression is simplified by first taking the square root of 25 to get 5, and then performing the operation 6 minus 5 divided by 4 to get the answer 4.75. The provided options do not match this result.
Step-by-step explanation:
The student has asked to simplify the expression: 6 - √25 / 4. First, we calculate the square root of 25, which is 5. The expression simplifies to 6 - 5 / 4. The operations follow the order of operations, so we divide 5 by 4 before subtracting from 6. The division of 5 by 4 equals 1.25 or 5/4. Therefore, 6 - 5/4 equals 6 - 1.25 which simplifies to 4.75. However, this answer is not listed among the options given (A) 2, (B) 1, (C) 0, (D) -1, and it's possible there may have been a typo in the original question or it could have been misinterpreted. Neither of the options matches the simplified result 4.75. Assuring proper parentheses and order of operations in the original question could clarify the intended operations and available options.
