Question

En el monomio: P(x; y) = (n–3)x4+n
y
n
, se cumple:
GR(x) + GR(y) + 5 = 19
Calcula el coeficiente.

Answer 1

P(x; y) = (n–3)x^4+ny^n

GR(x) = 4
GR(y) = n

GR(x) + GR(y) + 5 = 19 
4 + n + 5 = 19
n + 9 = 19
n = 10

Coef = n - 3 = 10 - 3 = 7

Answer 2

$P(x;y) = (n-3)x^{4}+ny^{n}$

GR(x) = 4
GR(y) = n

Ahora
GR(x) + GR(y) + 5 = 19 
     4   +     n     + 5 = 19
n + 9 = 19
n = 19-9
n = 10

Coeficiente = n - 3
coeficiente = 10-3
coeficiente = 7
