The sum or product of two irrational numbers can be a rational or an irrational number, depending on the specific numbers involved

The sum or product of two irrational numbers can be a rational or an irrational number, depending on the specific numbers involved.

1. Sum of irrational numbers:
Let’s consider two irrational numbers, a and b. Their sum, a + b, can be either rational or irrational.

Example 1: √2 + √3
The sum of √2 and √3 is irrational. It cannot be simplified or expressed as a fraction. Thus, the sum of two irrationals (√2 + √3) is irrational.

Example 2: √2 + (-√2)
In this case, the sum of √2 and its negative counterpart, -√2, is rational. When added together, they cancel each other out, resulting in zero, which can be expressed as a fraction. Therefore, the sum of two irrationals (√2 + (-√2)) is rational.

2. Product of irrational numbers:
The product of two irrational numbers can also be either rational or irrational.

Example 1: √2 × √3
The product of √2 and √3 is an irrational number. It cannot be expressed as a fraction, and its value is the square root of 6. So, the product of two irrationals (√2 × √3) is irrational.

Example 2: √2 × (1/√2)
Here, the product of √2 and its reciprocal, 1/√2, results in a rational number. √2 × (1/√2) simplifies to 1, which can be expressed as a fraction. Thus, the product of two irrationals (√2 × (1/√2)) is rational.

In conclusion, the sum or product of two irrational numbers can yield either a rational or an irrational number, depending on the specific values involved in the calculation.
