How do u show the group of digits that repeat ina resorting decimal

Answer 1

To show the group of digits that repeat in a resorting decimal, you can use a notation called the "bar notation". In this notation, a bar is placed over the group of digits that repeat. Here is an example:

1.234545454545...

In this example, the group of digits "4545" keeps repeating. To show this repetition, you can place a bar over the "45" like this:

1.234545̅

This indicates that the digits "45" repeat indefinitely in the decimal.
