## product of rational number and irrational number is

### When you multiply a rational number and an irrational number, the result will always be an irrational number

When you multiply a rational number and an irrational number, the result will always be an irrational number. This is because the product of a rational number (which can be expressed as a fraction) and an irrational number (which cannot be expressed as a fraction) will not be able to simplify or reduce to a rational number.

To understand this concept, let’s consider an example:

Let’s multiply the rational number 3/4 with the irrational number √2.

(3/4) * √2 = (3/4) * (√2)

To compute this multiplication, we can rationalize the denominator by multiplying the numerator and denominator by √2.

(3/4) * (√2) * (√2/√2) = (3/4) * (√2 * √2) / (√2)

Simplifying this expression gives us:

(3/4) * (2) / (√2)

Multiplying the numerators and denominators:

(3 * 2) / (4 * √2)

Simplifying further:

6 / (4√2)

We can simplify this expression by dividing both the numerator and denominator by 2:

3 / (2√2)

As you can see, the result of multiplying a rational number (3/4) with an irrational number (√2) is an expression that cannot be reduced further. Therefore, the product of a rational number and an irrational number is always an irrational number.
