Semoga bisa membantu...

Penyelesaian :

Yang A
[tex]2 \sqrt{32} + 5 \sqrt{72} \\ = 2 \sqrt{16 \times 2} + 5 \sqrt{36 \times 2} \\ = 8 \sqrt{2} + 30 \sqrt{2} \\ = (8 + 30) \sqrt{2} \\ = 38 \sqrt{2} [/tex]

Yang B
[tex] \sqrt{48} + \sqrt{27} - \sqrt{12} \\ = \sqrt{16 \times 3} + \sqrt{9 \times 3} - \sqrt{4 \times 3} \\ = 4 \sqrt{3} + 3 \sqrt{3} - 2 \sqrt{3} \\ = (4 + 3 - 2) \sqrt{3} \\ = 5 \sqrt{3} [/tex]
