Answer:

Answer: B. It is a perfect square

Step-by-step explanation:

Radical Expressions

Melissa multiplied $\sqrt{a}$ and $\sqrt{b}$ and got a rational number.

We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.

We can write that product like:

$\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}$

If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.

Answer: B. It is a perfect square
