Question:
Evaluate $\frac{\sqrt{48}}{\sqrt{243}}$
Solution:
$\frac{\sqrt{48}}{\sqrt{243}}$
$=\sqrt{\frac{48}{243}}$
$=\sqrt{\frac{2 \times 2 \times 2 \times 2 \times 3}{3 \times 3 \times 3 \times 3 \times 3}}$
$=\frac{\sqrt{2 \times 2 \times 2 \times 2}}{\sqrt{3 \times 3 \times 3 \times 3}}$
$=\frac{2 \times 2}{3 \times 3}$
$=\frac{4}{9}$
