bentuk sederhana dari√50-4√2+√18 ​

Answer 1

Jawaban:

[tex]4 \sqrt{2} [/tex]

Penjelasan dengan langkah-langkah:

[tex] \sqrt{50} - 4 \sqrt{2} + \sqrt{18} \\ = \sqrt{25 \times 2} - 4 \sqrt{2} + \sqrt{9 \times 2} \\ = 5 \sqrt{2} - 4 \sqrt{2} + 3 \sqrt{2} \\ = (5 - 4 + 3) \sqrt{2} \\ = 4 \sqrt{2} [/tex]

Answer 2

[tex]{\sf{1.) \: \sqrt{50} \: - \: 4 \sqrt{2} \: + \: \sqrt{18} }}[/tex]

[tex]{\sf{ = \: \sqrt{25 \: \times \: 2} \: - \: 4 \sqrt{2} \: + \: \sqrt{9 \: \times \: 2} }}[/tex]

[tex]{\sf{ = \: \sqrt{25} \: \times \: \sqrt{2} \: - \: 4 \sqrt{2} \: + \: \sqrt{9} \: \times \: \sqrt{2} }}[/tex]

[tex]{\sf{ = \: 5 \sqrt{2} \: - \: 4 \sqrt{2} \: + \: 3 \sqrt{2} }}[/tex]

[tex]{\bf{ = \:(5 \: - \: 4 \: + \: 3) \sqrt{2} }}[/tex]

[tex]{\bf{ = \: (1 \: + \: 3) \sqrt{2} }}[/tex]

[tex]\boxed{\sf{{ \bf{ = \: \boxed{\sf{{ \bf{4 \sqrt{2} }}}}}}}}[/tex]
