The product of a rational and irrational number is typically irrational.

Here's why:

1. A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, with the denominator q not equal to zero. For example, 1/2, 2, 7, etc.

2. An irrational number is a number that cannot be expressed as a ratio of two integers. In other words, it cannot be written as a simple fraction. For example, the square root of 2, pi, etc.

3. When you multiply a rational number (let's say 2) by an irrational number (like the square root of 2), the result is an irrational number (2 times the square root of 2).
