tentukan hasil dari [tex] \sqrt{18} - \sqrt{32 } + \sqrt{8} [/tex]

[tex] \sqrt{18} - \sqrt{32} + \sqrt{8} \\ \sqrt{9 \times 2} - \sqrt{16 \times 2} + \sqrt{4 \times 2} \\ 3 \sqrt{2} - 4 \sqrt{2} + 2 \sqrt{2} \\ \sqrt{2} [/tex]

√18 - √32 + √8
= √9.2 - √16.2 + √4.2
= 3√2 - 4√2 + 2√2
=  √2

semoga bantu
