Is 7 an irrational number?

Answer 1

No. #7# is not an irrational number.

An irrational number is a real number which cannot be expressed as #a/b# where #a# and #b# are integers. As #7/1 = 7# and #7# and #1# are integers, this means #7# is not an irrational number.

No, 7 is not an irrational number. It is a rational number because it can be expressed as a quotient of two integers, where the denominator is not zero. In the case of 7, it can be expressed as ( \frac{7}{1} ), where both 7 and 1 are integers. Therefore, 7 is a rational number.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
