Which value approximates the square root of 16?

• A. 4.00
• B. 4.05
• C. 4.10
• D. 4.15

Answer: (A)

The square root of a number is a value that, when multiplied by itself, gives the original number. For the number 16, the square root is found by determining which number, when squared, equals 16. In this case, 4 multiplied by 4 equals 16 (4 × 4 = 16). Therefore, the square root of 16 is exactly 4.00. The other choices provide numbers that are slightly higher than 4, none of which satisfy the requirement of being equal to the square root of 16 when squared. Thus, the value that accurately represents the square root of 16 is 4.00.
