Question

Jawaban dan cara penyelsaiannya no.5 dan 6

Answer 1

14/3-√2 x (3+√2)/(3+√2)
= (42 + 14√2)/(9-2)
= (42 + 14√2)/7
= 6 + 2√2

Answer 2

Nomor 5 :
14 / (3 - √2) x (3 + √2) / (3 + √2)
=(42 + 14√2) / 9 - 2
=(42 + 14√2) / 7
=6 + 2√2... opsi A

Nomor 6 :
(√3 + √2)(√3 - √2) / (2√2 - √3)
=(3 - 2) / (2√2 - √3)
=1 / (2√2 - √3) x (2√2 + √3) / (2√2 +√3)
= (2√2 + √3) / (8 - 3)
= (2√2 + √3) / 5
