Question

помогите пожалуйста.

Answer 1

22 p^4 q^2/99p5q = 22q/99p
7a/(a^2 + 5a) = 7a/a(a + 5) = 7/(a + 5)
(7x - 7y)/(x^2 - y^2) = 7(x - y)/(x - y)(x + y) = 7/(x + y)

Answer 2

$frac{22 p^{4} q^{2} }{99 p^{5}q } = frac{2q}{9p}$

$frac{4a}{ a^{2}+5a } = frac{4a}{a(a+5a)} = frac{4}{a+5a}$

$frac{7x-7y}{ x^{2} - y^{2} } = frac{7(x-y)}{(x+y)(x-y)} = frac{7}{x+y}$
