Question: A student claims that square root of (50)​ is close to 7.1 because 7.1^2=50.41. Another student says the estimate should be closer to 7.05. Which reasoning best supports which student is closer and why?
A) The second student is more accurate because 7.05^2=49.70, which is closer to 50 than 50.41.
B) The first student is more accurate because 7.1^2=50.41, which is higher than 50, and square root must round up.
C) Both students are wrong because square root of (50)​ is irrational and cannot be estimated.
D) The first student is correct because estimating irrational numbers is not possible without a calculator.
