Express $6\times \frac{5}{3}$ as a single fraction.
$$\frac{6\times 5}{3}\sqrt{236}$$
Multiply $6$ and $5$ to get $30$.
$$\frac{30}{3}\sqrt{236}$$
Divide $30$ by $3$ to get $10$.
$$10\sqrt{236}$$
Factor $236=2^{2}\times 59$. Rewrite the square root of the product $\sqrt{2^{2}\times 59}$ as the product of square roots $\sqrt{2^{2}}\sqrt{59}$. Take the square root of $2^{2}$.
