and how did you get this answer

1 answer

The examples of rational numbers among the given options are:

√4 + √16
2 * √4

To determine if a number is rational, we need to check if it can be expressed as a fraction of two integers (where the denominator is not zero). The first option, √4 + √16, can be simplified as 2 + 4, which is equal to 6. Therefore, it is a rational number.

The fourth option, 2 * √4, can be simplified as 2 * 2, which is equal to 4. Therefore, it is also a rational number.
