................

NOMOR 11 : C

[tex]2x {}^{5} {y}^{3} \div 10 {x}^{2} y \\ = \frac{2x {}^{5} {y}^{3} }{10 {x}^{2} y } = \frac{1 {x}^{3} {y}^{2} }{5} = \frac{ {x}^{3} {y}^{2} }{5} [/tex]

NOMOR 12 : D

[tex]5 {x}^{6} {y}^{2} \div 20 {x}^{5} {y}^{2} \\ = \frac{5 {x}^{6} {y}^{2} }{20 {x}^{5} {y}^{2} } = \frac{1 x }{4} = \frac{x}{4} [/tex]

SEMOGA MEMBANTU :)
