Question

what is the decimal expansion of irrational numbers

Answer 1

The decimal expansion of a numbermay terminate (in which case thenumber is called a regular number or finite decimal, e.g., ), eventually become periodic (in which case thenumber is called a repeating decimal, e.g., ), or continue infinitely without repeating (in which case the number is called irrational).

Answer 2

Answer:

Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers.

This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as the ratio of two whole numbers.

When expressed as a decimal, irrational numbers go on forever after the decimal point and never repeat.
