Answer

(a) $\sqrt{54} = 7.348469$ $3~\sqrt{6} = 7.348469$ (b) $\sqrt{\frac{5}{16}} = 0.55901699$ $\frac{\sqrt{5}}{4} = 0.55901699$

Work Step by Step

We can use a calculator to verify that the expressions are equivalent: (a) $\sqrt{54} = 7.348469$ $3~\sqrt{6} = 7.348469$ (b) $\sqrt{\frac{5}{16}} = 0.55901699$ $\frac{\sqrt{5}}{4} = 0.55901699$
