Answer

16

Work Step by Step

We first combine this into one square root: $\sqrt {8\times 32} = \sqrt {256}$ In order to see if a radical is in simplified form, see if any of its factors are perfect squares (meaning that their square root will be an integer). We see that 256 is a perfect square, so we know that we can simplify: $ \sqrt {256}=16$
