Rasionalkan penyebut dari bentuk akar berikut!
4-√2 /√5 + √2 ​

Materi : Bentuk Akar dan Pangkat

( 4 - √2 )/( √5 + √2 )

= ( 4 - √2 )( √5 - √2 )/( √5 + √2 )( √5 - √2 )

= ( 4√5 - 4√2 - √10 + [√2]² )/( [√5]² - [√2]² )

= ( 4√5 - 4√2 - √10 + 2 )/( 5 - 2 )

= ⅓( 2 - 4√2 + 4√5 - √10 )

Semoga bisa membantu
