\[(7\sqrt{8})(4\sqrt{5})\] With the help of the radical identity \(\sqrt{a.b}=\sqrt{a}.\sqrt{b}\) we can separate, but first, let's convert the 7 and the 4 as radicals: \[(\sqrt{49}\sqrt{8})(\sqrt{16}\sqrt{5})\] And then, applying the identity I spoke about we get: \[(\sqrt{49}\sqrt{8})(\sqrt{16}\sqrt{5}) \iff (\sqrt{(49)(8)})(\sqrt{(16)(5)})\] But then again, we can re-apply the identity since we still have the product of two radicals: \[(\sqrt{(49)(8)})(\sqrt{(16)(5)}) \iff \sqrt{(49)(8)(16)(5)}\] Al you have to do now is operate those multiplications inside the radical and you'll get the answer.

@Owlcoffee you may have confused me a little bit ha. The answer I came up with is wrong?

It's quite simple, when you want to express a radical into it's mosr simple form, you first express everything in one radical and then using the identity you can simplify it further: \[\sqrt{(49)(8)(16)(5)} \iff (7)(4)\sqrt{(8)(5)}\]
