5sqrt(3)

Explanation:

When multiplying radicals, you can just multiply the numbers under the root symbol and put them under a single root symbol.
Ex: sqrt(5) times sqrt (15) = sqrt (5 times 15)
Thus, this can be rewritten as sqrt (25 times 3)
This is the same as sqrt(25) times sqrt (3)
The square root of 25 is 5, so the final answer is
5sqrt(3)
