Question

Is radical 3 times radical 3 equals to radical 9? Yes/No

Answer 1

$\sqrt{m} * \sqrt{n} = \sqrt{mn} = \\ \sqrt{3}* \sqrt{3}= \sqrt{9}$
Answer: Yes

Answer 2

we know that

radical $3$ is equal to

$\sqrt{3} =3^{\frac{1}{2}}$

so

$\sqrt{3}*\sqrt{3} =3^{\frac{1}{2}} *3^{\frac{1}{2}} \\ =(3*3)^{\frac{1}{2}} \\= (9)^{\frac{1}{2}}=\sqrt{9}$

therefore

the answer is

Yes
