Answer 1

$1);;frac{361}{400}m^2-n^{10} = frac{19}{20}^2m^2-(n^5)^2 = \ \ = (frac{19}{20}m)^2 - (n^5)^2 = (frac{19}{20}m - n^5)(frac{19}{20}m + n^5)\\2);; c^6-frac{289}{324}d^4 = (c^3)^2 - (frac{17}{18})^2(d^2)^2 = (c^3)^2 - (frac{17}{18}d^2)^2 =\ \ = (c^3-frac{17}{18}d^2)(c^3+frac{17}{18}d^2)\ \ 3) 5.76x^{12}-frac{4}{81}y^8 = 2.4^2(x^6)^2-(frac{2}{9})^2(y^4)^2 = (2.4x^6)^2-(frac{2}{9}y^4)^2 =\ \ =(2.4x^6-frac{2}{9}y^4)(2.4x^6+frac{2}{9}y^4)$
