Question

помогите плиз) оч прошу)

Answer 1

$cfrac{18x^2y}{24xy^3}= cfrac{3x}{4y^2}$

$cfrac{6x-2x^2}{2x-6} = cfrac{-x(2x-6)}{2x-6}=-x$

$cfrac{4x^2-1}{1-4x+4x^2} = cfrac{(2x-1)(2x+1)}{(2x-1)^2} = cfrac{2x+1}{2x-1}$

$cfrac{m^3+8n^3}{2n+m} = cfrac{(m+2n)(m^2-2mn+4n^2)}{2n+m}=m^2-2mn+4n^2$

$cfrac{2^{n+1}cdot x-2^{n+2}}{2^ncdot x^2-2^{n+2}} = cfrac{2x-2^2}{x^2-2^2} = cfrac{2(x-2)}{(x-2)(x+2)} = cfrac{2}{x+2}$

Answer 2

чё это такое? $cfrac{2^{n+1}cdot x-2^{n+2}}{2^ncdot x^2-2^{n+2}} = cfrac{2x-2^2}{x^2-2^2} = cfrac{2(x-2)}{(x-2)(x+2)} = cfrac{2}{x+2}$
