Question

Запишите частное в виде дроби и сократите дробь: 1) -6ax : (-18ax); 2) 6ab² : (9bc²); 3) 3day : (6ay³); 4)-32b^5c : (12b^4·C²) 5) (6xy-18x²) : (y-3x)³.

Answer 1

$\displaystyle 1)..-6ax:(-18ax)= \frac{-6ax}{-18ax}= \frac{6}{18}= \frac{1}{3} \\ \\ 2)..6ab^{2}:(9bc^{2})= \frac{6ab^{2}}{9bc^{2}}= \frac{2ab}{3c^{2}} \\ \\ 3)..3day:(6ay^{3})= \frac{3day}{6ay^{3}}= \frac{d}{2y^{2}} \\ \\ 4)..-32b^{5}c:(12b^{4}c^{2})=- \frac{32b^{5}c}{12b^{4}c^{2}}=- \frac{8b}{3c} \\ \\ 5)..(6xy-18x^{2}):(y-3x)^{3}= \frac{6x(y-3x)}{(y-3x)^{3}}= \frac{6x}{(y-3x)^{2}}$

Answer 2

Чувак, все кроме 5,я с кубом разности и суммы путаюсь ((

Answer 3

1. -6ax : (-18ax) = 1/3

2. 6ab² : (9bc²) = 2a/3c

3. 3day : (6ay³) = 1/2y²

4. -32b^5c : (12b^4·C²) = -8b/c

5. (6xy-18x²) : (y-3x)³ = (2x(3y-9x)) / (y-3x)³ = -2x / (y-3x)²
