Answer 1

Respuesta:

Explicación paso a paso:

$R=\frac{(3m+2n)^{2}+(3m-2n)^{2} }{9m^{2}+4n^{2} }$

$R=\frac{(3m^{2}+2*3m*2n+2n^{2})+(3m^{2}-2*3m*2n+2n^{2}) }{9m^{2}+4n^{2} }$

$R=\frac{(9m+6m*2n+4n)+(9m-6m*2n+4n)}{81m+16n}$

$R=\frac{(15m*6n)+(3m*6n)}{81m+16n}$

Answer 2

Respuesta:

R = 2

Explicación paso a paso:

$R = \frac{(9m^{2}+(2)(3m)(2n)+4n^{2}) + (9m^{2}-(2)(3m)(2n)+4n^{2})}{9m^{2}+4n^{2} }$

$R=\frac{(9m^{2}+12mn+4n^{2}) + (9m^{2}-12mn+4n^{2})}{9m^{2} +4n^{2} }$

$R=\frac{9m^{2}+4n^{2} + 9m^{2}+4n^{2}}{9m^{2} +4n^{2} }$

$R=\frac{18m^{2}+8n^{2}}{9m^{2} +4n^{2} }$

$R=\frac{2(9m^{2}+4n^{2})}{9m^{2} +4n^{2} }$

$R=2$

Buena suerte!!!!!!!!!!!!!!
