This is a discussion on Connections Academy Algebra Readiness; Lesson 10 Unit 3.

Question

Student A believes the square root of 2 over 8 is a rational number because it can be written as a fraction.

Student B believes that the square root of 2 over 8 is an irrational number because, the square root of 2 is irrational.

My answer: Student A is correct because the square root of 2 is 4, 4 is a rational number. 4/8 is a rational number because it can be written as a non-repeating decimal. Student B is incorrect because the square root of 2 is not an irrational number.

pls tell me if this is correct because everyone else on the discussion is saying Student B is correct and Student A is incorrect. Thx <3
