I just did a quick internet search because I wasn't sure it radicals had to be irrational. If they did then you question would have no answer.
But I found no evidence that this was the case so there are many answers.
$$\sqrt{8.7\times8.7}=\sqrt{75.69}\\\\
\sqrt{8.7\times8.7\times8.7}=\sqrt[3]{658.503}\\\\$$
These are just 2 of the answers.
anyone want to comment?
