sederhanakanlah akar 121/441 dan akar 320/1000

[tex] \sqrt{ \frac{121}{441} } = \frac{ \sqrt{121} }{ \sqrt{441} } = \frac{11}{21} [/tex]
dan
[tex] \sqrt{ \frac{320}{1000} } \\ = \frac{ \sqrt{320} }{ \sqrt{1000} } \\ = \frac{ \sqrt{64 \times 5} }{ \sqrt{100 \times 10} } \\ = \frac{8 \sqrt{5} }{10 \sqrt{10} } \\ =\frac{8 \sqrt{5} }{10 \sqrt{10} } \times \frac{ \sqrt{10} }{ \sqrt{10} } \\ = \frac{8 \sqrt{50} }{100} \\ = \frac{8 \sqrt{25 \times 2} }{100} \\ = \frac{8.5 \sqrt{2} }{100} \\ = \frac{40 \sqrt{2} }{100} \\ = \frac{2 \sqrt{2} }{5} \\[/tex]
