Jawab no 16 ………​

Jawaban:

6

Penjelasan dengan langkah-langkah:

= (√11 + √5) (√11 – √5)

= (√11 . √11) + (√11 . -√5) + (√5 . √11) + (√5 . -√5)

= 11 – √55 + √55 – 5

= 11 – 5

= 6

Jawaban:

( sqrt{11} + sqrt{5} )( sqrt{11} - sqrt{5} ) = ( sqrt{11} times sqrt{11 }) + ( sqrt{11} times ( - sqrt{5} )) + ( sqrt{5} times sqrt{11} ) + ( sqrt{5} times ( - sqrt{5} )) = sqrt{121} - sqrt{55} + sqrt{55} - sqrt{25} = 11 - 5 = 6 \

semoga membantu ^_^
