Question

плиз срочно!!
8) -11x/4y^2: (-22x2)
10) 14/9x^3:7x/2y^2
12)28a^3:18a^4/7b^2
pleas ​

Answer 1

Объяснение:

8) (-11x/4y^2) / (-22x^2) = (11x/4y^2) * (1/2x) = (11/8y^2)

10) (14/9x^3) / (7x/2y^2) = (14/9x^3) * (2y^2/7x) = (4y^2/9x^2)

12) 28a^3 / (18a^4/7b^3) = 28a^3 * (7b^3/18a^4) = 7b^3/9a
