[tex]12 \sqrt{2} [/tex]
2.
[tex]11 \sqrt{2} [/tex]
3. 5 orang
4. 6225/162= 38,425..liter
Penjelasan dengan langkah-langkah:
1.
[tex] \sqrt{48} \times \sqrt{6} \\ = \sqrt{48 \times 6} \\ = \sqrt{288} \\ = \sqrt{2} \times \sqrt{144} \\ = 12 \sqrt{2} [/tex]
2.
[tex] \sqrt{32} - \sqrt{2} + \sqrt{128} \\ = \sqrt{16} \times \sqrt{2} - \sqrt{2} + \sqrt{64} \times \sqrt{2} \\ = 4 \sqrt{2} - \sqrt{2} + 8 \sqrt{2} \\ = (4 - 1 + 8) \sqrt{2} \\ = 11 \sqrt{2} [/tex]
3.
15/9= x/12
15×12= 9x
180= 9x
x= 20
Pekerja tambahan= 20-15= 5 orang
4.
162/415= 15/x
162x= 415×15
162x= 6225
x= 6225/162
x= 38,425 liter
