Answer

(a) $\sqrt{48} = 6.9282$ $4~\sqrt{3} = 6.9282$ (b) $\sqrt{\frac{7}{9}} = 0.881917$ $\frac{\sqrt{7}}{3} = 0.881917$

Work Step by Step

We can use a calculator to verify that the expressions are equivalent: (a) $\sqrt{48} = 6.9282$ $4~\sqrt{3} = 6.9282$ (b) $\sqrt{\frac{7}{9}} = 0.881917$ $\frac{\sqrt{7}}{3} = 0.881917$
