= (3√6+2√5) / (√6+√5) x (√6-√5) / (√6-√5)
= 18 - 3√30 + 2√30 - 10 / 6 - 5
= 18 - 10 -3√30 + 2√30 / 1
= 8 - 5√30
b. (3p+q)/3q
= { 3(2+√3) + (2-√3) } / 3(2-√3)
= (6 + 3√3 + 2 - √3) / (6 - 3√3)
= (8 + 2√3) / (6 - 3√3)
= (8 + 2√3 ) / (6 - 3√3) x (6 + 3√3) / (6 + 3√3)
=(48+ 24√3 + 12√3 + 18) / (36 - 27)
= 66 + 36√3 / 9
maaf kalo salah:)
