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:
[tex]( \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 \\ [/tex]
semoga membantu ^_^
