Tolong bantuin dong kak..bsk mau dikumpulin soalnya..pake cara yaa​

Penjelasan dengan langkah-langkah:

.

a) : frac{3}{ sqrt{3} + sqrt{2} }

 = frac{3}{ sqrt{3} + sqrt{2} } times frac{ sqrt{3} - sqrt{2} }{ sqrt{3} - sqrt{2} }

 = frac{3 sqrt{3} - 3 sqrt{2} }{3 - 2}

= frac{3 sqrt{3} - 3 sqrt{2} }{1} = 3 sqrt{3} - 3 sqrt{2}

.

b) : frac{ sqrt{3} }{ sqrt{12} - sqrt{3} }

 = frac{ sqrt{3} }{ sqrt{12} - sqrt{3} } times frac{ sqrt{12} + sqrt{3} }{ sqrt{12} + sqrt{3} }

 = frac{ sqrt{36} + 3}{12 - 3}

 = frac{6 + 3}{9} = frac{9}{9} = 1

.

c) : frac{4 - 3 sqrt{2} }{4 + 3 sqrt{2} }

 = frac{4 - 3 sqrt{2} }{4 + 3 sqrt{2} } times frac{4 - 3 sqrt{2} }{4 - 3 sqrt{2} }

 = frac{16 - 12 sqrt{2} - 12 sqrt{2} + 18}{16 - 18}

 = frac{34 - 24 sqrt{2} }{ - 2}

 = - 17 + 12 sqrt{2}

.

d) : frac{ sqrt{2} }{ sqrt{5} + sqrt{3} }

 = frac{ sqrt{2} }{ sqrt{5} + sqrt{3} } times frac{ sqrt{5} - sqrt{3} }{ sqrt{5} - sqrt{3} }

 = frac{ sqrt{10} - sqrt{6} }{5 - 3}

 = frac{ sqrt{10} - sqrt{6} }{2}

.

semoga membantu
