Question

помогите прошу, желательно ещё объяснить :3​

Answer 1

$1)4a^{2}=(2a)^{2}\\\\9b^{2} =(3b)^{2}\\\\16c^{2}=(4c)^{2}\\\\0,04x^{2}=(0,2x)^{2}\\\\\\2)\frac{1}{9}a^{2}b^{2}=(\frac{1}{3}ab)^{2}\\\\0,25x^{2} y^{2}=(0,5xy)^{2}\\\\0,16m^{4} =(0,4m^{2})^{2}\\\\0,81n^{6}=0,9n^{3})^{2}\\\\\\3)0,01a^{4} b^{2}=(0,1a^{2}b)^{2}\\\\\frac{9}{16}x^{2}y^{4}=(\frac{3}{4}xy^{2})^{2} \\\\\frac{25}{49}x^{6}z^{4}=(\frac{5}{7} x^{3} z^{2})^{2}$

$1\frac{9}{16}m^{4} n^{6}=\frac{25}{16}m^{4} n^{6}=(\frac{5}{4}m^{2}n^{3})^{2}=(1,25m^{2}n^{3})^{2}$
