Answer

30

Work Step by Step

We first combine this into one square root: $ \sqrt {12 \times 75} =\sqrt {900}$ We see if any of the factors of a radical are perfect squares (meaning that their square root will be an integer) to see if the radical is in its most simplified form. Because 900 is a perfect square, we know that we can simplify: $ \sqrt {900}=30$
