4√27-5√3
3√12+2√50-²√72![]()
3√12+2√50-²√72
4. -2√3
5. 2√3+4√2
Penjelasan dengan langkah-langkah:
[tex]4. \sqrt{27} - 5 \sqrt{3} [/tex]
[tex] = \sqrt{9} \times \sqrt{3} - 5 \sqrt{3} [/tex]
[tex] = 3 \sqrt{3} - 5 \sqrt{3} = - 2 \sqrt{3} [/tex]
[tex]5. \sqrt{12} + 2 \sqrt{50} - \sqrt[2]{72} [/tex]
[tex] = \sqrt{4} \times \sqrt{3} + 2 \times \sqrt{25} \times \sqrt{2} - \sqrt{36} \times \sqrt{2} [/tex]
[tex] = 2 \sqrt{3} + (2 \times 5) \sqrt{2} - 6 \sqrt{2} [/tex]
[tex] = 2 \sqrt{3} + 10 \sqrt{2} - 6 \sqrt{2} [/tex]
[tex] = 2 \sqrt{3} + 4 \sqrt{2} [/tex]
semoga membantu
