Tolong dibantu kak
Jawaban:
4/√6 = 4(√6) / √6(√6) = (4√6) / 6 = (2√6)/3
....
8/3√2 = 8(3√2) / 3√2(3√2) = (24√2) / 18 = (4√2)/3
.....
7/3√2 - 5 = 7(3√2 + 5) / 3√2 - 5(3√2 + 5)
= (21√2 + 35) / (18 - 25)
= (21√2 + 35) / -7
= -3√2 - 5
.....
√2/√2 + √7
= √2(√2 - √7) / √2 + √7(√2 - √7)
= 2 - √14 / 2 - 7
= 2 - √14 / -5
