Question

Помогите пожалуйста решить ! Заранее спасибо !

Answer 1

$x^2y^2-16=(xy-4)(xy+4) \ 36-a^2b^2=(6-ab)(6+ab) \ m^2n^2-0.09=(mn-0.3)(mn+0.3) \ frac{16}{25}-k^2p^2= (frac{4}{5}-kp)( frac{4}{5}+kp)$

$0.81p^2-4a^2b^2=(0.9p-2ab)(0.9p+2ab) \ 9m^2n^2-0.01p^2=(3mn-0.1p)(3mn+0.1p) \ 0.04k^2-0.09a^2n^2=(0.2k-0.3an)(0.2k+0.3an) \ frac{1}{9}a^2b^2-2 frac{7}{9}m^2p^2=( frac{1}{3}ab-frac{5}{3}mp)( frac{1}{3}ab++ frac{5}{3}mp)$
