Answer 2

Jawaban:

Penyelesaian :

[tex] \sf \sqrt{50} - \sqrt{72} + 2 \sqrt{18} - \sqrt{8} [/tex]

[tex] \sf = \sqrt{50} - \sqrt{72} + 2 \sqrt{9 \times 2} - \sqrt{4 \times 2} [/tex]

[tex] \sf = \sqrt{50} - \sqrt{72} + 2( \sqrt{9} \times \sqrt{2} ) - \sqrt{4} \times \sqrt{2} [/tex]

[tex] \sf = \sqrt{50} - \sqrt{72} + 2(3 \sqrt{2} ) - 2 \sqrt{2} [/tex]

[tex] \sf = \sqrt{50} - \sqrt{36 \times 2} + 6 \sqrt{2} - 2 \sqrt{2} [/tex]

[tex] \sf = \sqrt{50} - \sqrt{36} \times \sqrt{2} + 6\sqrt{2} - 2 \sqrt{2} [/tex]

[tex] \sf = \sqrt{25 \times 2} - 6 \sqrt{2} + 6 \sqrt{2} - 2 \sqrt{2} [/tex]

[tex] \sf = \sqrt{25} \times \sqrt{2} - 6 \sqrt{2} + 6 \sqrt{2} - 2 \sqrt{2} [/tex]

[tex] \sf = 5 \sqrt{2} - 6 \sqrt{2} + 6 \sqrt{2} - 2 \sqrt{2} [/tex]

[tex] \sf = 5 \sqrt{2} - 6 \sqrt{2} + 4 \sqrt{2} [/tex]

[tex] \sf = 3 \sqrt{2} [/tex]
