N = (2x + 5y)?
M = (7m? - 1)?

Ayuda olías el signo ? significa elevado a 2 es q no se puede poner​

Answer 1

Respuesta:

$R = (x - y) \\ =(x + y)</p><p> \\ S = (m + 2n {}^{2} ) {}^{2} \\ </p><p> = m {}^{2} +4n {}^{4} \\ N = (2x + 5y) {}^{2} \\ = 4x ^{2} + 25y {}^{2} \\ </p><p>M = (7m {}^{2} - 1) {}^{2} \\ = 49m {}^{4} - 1$
