Answer 2

Answer:

C) Rational or Irrational

Step-by-step explanation:

Let's check this with the help of examples:

1. First number = 2

  Second Number = 4

In this example First number is 2 which is a non-zero number rational and the other number is 4 which is a rational number

And their product is 4 x 2 = 8 which is a rational number

2. First number = $\sqrt{3}$

  Second number = 2

In this case $\sqrt{3}$ is a non zero irrational number and 2 is a rational number.

But their product is 2$\sqrt{3}$ and it's irrational.

The results are -

It can be both rational or irrational!

Hope you get it!

Good Luck!
