Question

0.101001000100001000001.... is a rational number or what
​

Answer 1

Answer:

This decimal is obviously not finite, so if it is rational, the decimal repeats with period p. However, somewhere after the repeating starts, we get a string of 0's followed by a 1 of length greater than p. Hence the number is irrational.

Answer 2

Answer:

it is a rational number as it can be presented in the form of p/q
