5 akar 2 kurang 9 akar 2


tolong Jawab kak​

Jawaban:

[tex]5 \sqrt{2} - 9 \sqrt{2} = \sqrt{5 \times 5 \times 2} - \sqrt{9 \times 9 \times 2} = \sqrt{25 \times 2} - \sqrt{81 \times 2} = \sqrt{50} - \sqrt{162} = \sqrt{50 - 162} = \sqrt{ - 112} [/tex]

semoga membantu (:

Penyelesaian :

[tex] {5}^{2} - {9}^{2} \\ \\ = 5 \times 5 - 9 \times 9 \\ \\ = 25 - 81 \\ \\ \boxed{ \boxed{ \blue{ = -56}}}[/tex]
