Rasionalkan bentuk pecahan berikut:

2/3+2 akar 2 dikali 3-2 akar 2/3-2 akar 2=6-2 akar 2/7
sekian

a. 2/ 3+2√2 × 3-2√2/ 3-2√2
= 2(3-2√2)/ 9-4.2
= 2(3-2√2)/ 1
= 2(3-2√2) atau 6-4√2
b. √6+√2/ √6-√2 × √6+√2/ √6+√2
= (√6+√2)(√6+√2)/ 6-2
= 6+√12+√12+2/ 4
= 8+2√12/ 4
= 8+2√4.3/ 4
= 8+2.2√3/ 4
= 8+4√3/ 4
= 4(2+√3)/ 4
= 2+√3
