Step1: Factor the radicand
We need to factor 160 into a product of a perfect square and another number. We know that \(160 = 16\times10\), where 16 is a perfect square (\(4^2 = 16\)).
\[
\sqrt{160}=\sqrt{16\times10}
\]
Step2: Use the property of radicals
Using the property \(\sqrt{ab}=\sqrt{a}\times\sqrt{b}\) (where \(a\geq0\) and \(b\geq0\)), we can split the radical:
\[
\sqrt{16\times10}=\sqrt{16}\times\sqrt{10}
\]
Step3: Simplify the perfect square radical
Since \(\sqrt{16} = 4\) (because \(4^2=16\)), we substitute that in:
\[
\sqrt{16}\times\sqrt{10}=4\sqrt{10}
\]

\(4\sqrt{10}\) (or in the boxed form as per the question's structure, the first box is 16, the second box is 10, and the simplified form is \(4\sqrt{10}\); but following the step - by - step, the simplified radical is \(4\sqrt{10}\))
