даю 100 балов​

Answer 1

$\frac{9}{16}m^2+2mn+\frac{16}{9}n^2=\\\\\left(\frac{3}{4}m\right)^2+2mn+\left(\frac{4}{3}n\right)^2=\\\\ \underline {\left(\frac{3}{4}m+\frac{4}{3}n\right)^2}$

$b^2-2a^2b+a^4=\\\\b^2-2a^2b+(a^2)^2=\\\\\underline{(b-a^2)^2}$

$9a^2+6ab+b^2=\\\\(3a)^2+6ab+b^2=\\\\\underline{(3a+b)^2}$

$0,64p^2+1,6pz+z^2=\\\\(0,8p)^2+1,6pz+z^2=\\\\\underline{ (0,8p+z)^2}$
