Rasionalkan penyebut pecahan-pecahan berikut ini A. √2/√6 B. 3/√5-√2 C. √3-√5/√3+√5 Mohon bantuannybsk harus udh dikumpulin Sebelum jam 7 pagi Pake caranya ya m

[tex]a) \frac{ \sqrt{2} }{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} } \\ = \frac{ \sqrt{12} }{6} \\ = \frac{2 \sqrt{3} }{6} \\ = \frac{1}{3} \sqrt{3} [/tex]
[tex] b)\frac{3}{ \sqrt{5} - \sqrt{2} } \times \frac{ \sqrt{5} + \sqrt{2} }{ \sqrt{5} + \sqrt{2} } \\ = \frac{3( \sqrt{5} + \sqrt{2} )}{5 - 2} \\ = \frac{3( \sqrt{5} + \sqrt{2}) }{3} \\ = \sqrt{5 } + \sqrt{2} [/tex]
[tex]c) \frac{ \sqrt{3} - \sqrt{5} }{ \sqrt{3} + \sqrt{5} } \times \frac{ \sqrt{3} - \sqrt{5} }{ \sqrt{3} - \sqrt{5} } \\ = \frac{( \sqrt{3} - \sqrt{5} ) {}^{2} }{3 - 5} \\ = \frac{3 - 2\sqrt{15} + 5 }{ - 2} \\ = \frac{ - 2 \sqrt{15} + 2}{ - 2} \\ = \frac{ - 2( \sqrt{15} - 2) }{ - 2} \\ = \sqrt{15} - 2[/tex]
semoga membantu......
