2√2 = 8 :8 = 1
√48 =48 : 8 = 6
2√2 per √48 mungkin 1/6 √6

mungkin loo....

√48 = √8 . √6
√8 = √2² . 2 = 2√2

jadi, \frac{2 \sqrt{2} }{ \sqrt{48} }= \frac{2 \sqrt{2} }{ \sqrt{8} . \sqrt{6} } =  \frac{2 \sqrt{2} }{ \sqrt{ 2^{2} .2} . \sqrt{6} }= \frac{2 \sqrt{2} }{ 2 \sqrt{2} . \sqrt{6} } =  \frac{1}{ \sqrt{6} }

kalau dirasionalkan, jadi  \frac{1}{ \sqrt{6} } . \frac{ \sqrt{6} }{ \sqrt{6} } =  \frac{ \sqrt{6} }{6} = \frac{1}{6}   \sqrt{6}
