Q. Which of the following is an integer?Choices:(A) 6β(B) Ο(C) 2β(D) 6
Evaluate choices for integers: We need to evaluate each choice to determine if it is an integer.
Choice (A) - 6β: Choice (A) is 6β. The square root of 6 is not an integer because 6 is not a perfect square (the perfect squares closest to 6 are 4 and 9, which are the squares of 2 and 3, respectively).
Choice (B) - Ο: Choice (B) is Ο (pi). Pi is a well-known mathematical constant that represents the ratio of the circumference of a circle to its diameter. Pi is an irrational number, not an integer.
Choice (C) - 2β: Choice (C) is 2β. The square root of 2 is not an integer because 2 is not a perfect square (the perfect squares closest to 2 are 1 and 4, which are the squares of 1 and 2, respectively).
Choice (D) - 6: Choice (D) is 6. The number 6 is an integer because it is a whole number that can be written without a fractional or decimal component.
