1. Si [tex]\( m \, n = (m+n)^2 - 156 \)[/tex], calcula el valor de 412.

Sagot :

Claro, vamos a resolver la expresión dada paso a paso.

Dada la ecuación:

[tex]\[ m n = (m + n)^2 - 156 \][/tex]

Primero, vamos a identificar los valores de [tex]\( m \)[/tex] y [tex]\( n \)[/tex]. Sabemos que:

[tex]\[ m = 412 \][/tex]
[tex]\[ n = 156 \][/tex]

Procedamos paso a paso:

1. Suma de [tex]\( m \)[/tex] y [tex]\( n \)[/tex]:
[tex]\[ m + n = 412 + 156 \][/tex]
[tex]\[ m + n = 568 \][/tex]

2. Elevamos la suma al cuadrado:
[tex]\[ (m + n)^2 = 568^2 \][/tex]

3. Ahora, restamos 156 del cuadrado de la suma:
[tex]\[ (m + n)^2 - 156 = 568^2 - 156 \][/tex]

El resultado de esta operación es:

[tex]\[ m n = 322468 \][/tex]

Así que, después de realizar todos los pasos anteriores, encontramos que el valor es [tex]\( 322468 \)[/tex].
