Jawab:
[tex]5\sqrt{2}[/tex]
Penjelasan dengan langkah-langkah:
[tex]\sqrt{72} - 2 \sqrt{18} + \sqrt{50} = \sqrt{36 \times 2} - 2 \sqrt{9 \times 2} + \sqrt{25\times 2}[/tex]
[tex]= 6\sqrt{ 2} - 2 (3\sqrt{2}) + 5\sqrt{2}\\ \\= 6\sqrt{ 2} - 6\sqrt{2} + 5\sqrt{2}\\ \\= 5\sqrt{2}[/tex]
√72 - 2√18 + √50
= √36x2 - 2.√9x2 + √25x2
= 6√2 - 2.3√2 + 5√2
= 6√2 - 6√2 + 5√2
= 5√2
