Answer
$\approx 2.8$
Work Step by Step
Using $\sqrt{2}=1.41$ and the properties of radicals, the given expression, $
\sqrt{8}
,$ evaluated to the nearest tenth, is equal to:
\begin{array}{l}\require{cancel}
\sqrt{4\cdot2}
\\\\=
\sqrt{(2)^2\cdot2}
\\\\=
2\sqrt{2}
\\\\=
2(1.41)
\\\\
\approx 2.8
.\end{array}
