Question

si
$mn ^{2} - nm^{2} = 1188$
Calcula el valor de m + n
​

Answer 1

Explicación paso a paso:

(10m+n-10n-m)(10m+n+10n+m)=1188

resolvemos:

(9m-9n)(11m+11n)=1188

simplificar:

(m-n) (m+n)=12

2 6

3 4

menor valor de m+n= 4

Answer 2

Respuesta:

m+n=6

Explicación paso a paso:

(10m+n-10n-m)(10m+n+10n+m)=1188

 (9m-9n)(11m+11n)=1188

9(m-n) 11(m+n)=1188

(m-n) (m+n)=12

2           6

m+n=6
