Jawaban:

$sqrt{12} + sqrt{27} + sqrt{75} = sqrt{4 times 3} + sqrt{9 times 3} + sqrt{25 times 3} \ = 2 sqrt{3} + 3 sqrt{3} + 5 sqrt{3} \ = 10 sqrt{3}$

$sqrt{10} + sqrt{15} + sqrt{20} = sqrt{2 times 5} + sqrt{3 times 5} + sqrt{4 times 5} \ = sqrt{5} ( sqrt{2} + sqrt{3} + 2)$

$( sqrt{3} + sqrt{5} )( sqrt{3} + sqrt{5}) = 3 + 2 sqrt{15} + 5 \ = 8 + 2 sqrt{15}$

$frac{20}{ sqrt{8} - sqrt{3} } = frac{20}{ sqrt{8} - sqrt{3} } times frac{ sqrt{8} + sqrt{3} }{ sqrt{8} + sqrt{3} } \ = frac{20( sqrt{8} + sqrt{3} )}{8 - 3} \ = frac{20 (sqrt{8} + sqrt{3} )}{5} \ = 4 sqrt{8} + 4 sqrt{3} \ = 8 sqrt{2} + 4 sqrt{3}$

$frac{ sqrt{3} }{2 sqrt{2} + 3 } = frac{ sqrt{3} }{2 sqrt{2} + 3} times frac{2 sqrt{2} - 3 }{2 sqrt{2} - 3} \ = frac{2 sqrt{6} - 3 sqrt{3} }{8 - 3} \ = frac{2 sqrt{6} - 3 sqrt{3} }{5}$

maaf fotonya ke crop, oiya tips : hafalin sifat sifat akar deh, nanti pasti bisa.

thankyou 😀
