Answer 2

The Problem

The problem states that there are four cards, each containing a letter on one side and a number on the other side. We need to determine which two cards to flip in order to verify the truth or falsehood of the following statement: "э к 8 9".

Analyzing the Statement

To analyze the statement, let's break it down into two parts: the letters and the numbers.

1. Letters: The statement includes the letters "э" and "к". We need to find the cards that have these letters on one side.

2. Numbers: The statement includes the numbers 8 and 9. We need to find the cards that have these numbers on one side.

Finding the Cards

To determine which two cards to flip, we need to find the cards that have the letters "э" and "к" on one side, as well as the cards that have the numbers 8 and 9 on one side.

Unfortunately, the search results did not provide any specific information about the cards or their contents. Therefore, we cannot determine which two cards to flip based on the given information.

Conclusion

Without additional information about the cards and their contents, it is not possible to determine which two cards to flip in order to verify the truth or falsehood of the statement "э к 8 9".
