D. 3.4 and 3.5

Answer 1

The square root of 15 is approximately 3.87, so the correct range it falls between is 3.8 and 3.9, not between any of the provided ranges in the options.

Step-by-step explanation:

The student appears to be confused about the subject matter. When the student mentions the square of 15, they likely mean the square root of 15, not 15 squared. The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 25 is 5 because 5 times 5 equals 25. The square root of 15 is approximately 3.87. Thus, the correct answer to what the square root of 15 is between is 3.8 and 3.9, meaning none of the provided options (A, B, C, or D) is correct since they all suggest a value lower than 3.8.
