Penjelasan dengan langkah-langkah:
1)
[tex] \bf \frac{10x {}^{7 }y {}^{5} }{5x {}^{7} y {}^{4} } [/tex]
[tex] \bf \frac{10 \cancel{x {}^{7}}y {}^{5} }{5 \cancel{x {}^{7}}y {}^{4} } [/tex]
[tex] \bf \frac{(10 \div 5)y {}^{5} }{y {}^{4} } [/tex]
[tex] \bf \frac{2 {y}^{5} }{y {}^{4} } [/tex]
[tex] \bf2y {}^{5 - 4} [/tex]
[tex] \bf2y {}^{1} [/tex]
[tex] \bf2y[/tex]
2)
[tex] \bf \frac{14x {}^{7}y {}^{15} }{21 {x}^{2} {y}^{3} } [/tex]
[tex] \bf \frac{ \cancel{14} \cancel{x {}^{7}} \cancel{y {}^{15} } }{ \cancel{21} \cancel{x {}^{2}} \cancel{y {}^{3} }} [/tex]
[tex] \bf \frac{2x {}^{5}y {}^{12} }{3} [/tex]
Jawaban:
- B
[tex] \frac{ 10 {x}^{7} y^{5} }{5 {x}^{7} {y}^{4} } \\ = \frac{ {2x}^{7} {y}^{4} }{ {x}^{7} {y}^{4} } \\ = \frac{2y}{1} \\ = 2y[/tex]
- C
[tex] \frac{14x^{7} {y}^{15} }{ {21x}^{2} {y}^{3} } \\ = \frac{ {2x}^{7} {y}^{15} }{ {3x}^{2} {y}^{3} } \\ = \frac{ {2x}^{5} {y}^{12} }{ {3}^{1} } \\ = \frac{ {2x}^{5} {y}^{12} }{3} [/tex]
