Binomios

Ejercicio 2 foro 7

Largo = A = x^2+2xy+y^2

Ancho = B =x+y

binomios

Área = (x^2+2xy+y^2 )(x+y)

Solucion

(x^2+2xy+y^2 )= 〖(x+y)〗^2

=〖(x+y)〗^2 ∙(x+y)= (x+y)∙(x+y)∙(x+y)

Entonces el Area del rectángulo es = 〖(x+y)〗^3

(25 x 36 x a^12 x3^3 x3^(-1))/(5^4 x〖 6〗^(10 ) x a^10 x〖 3〗^2 ) = (5^2 x 6^(2 ) x a^(12 ) x 3^3 x 3^(-3))/(5^(4 ) x 6^(10 ) x〖a 〗^(10 ) x〖 3〗^2 ) = (5^(2 ) x 6^(2 ) x〖 a〗^(12-10 ) x〖 3〗^(3-2-1))/(5^(4 ) x 6^10 ) =

5^(2-4) x 6^(2-10) x a^2 x 3^0 = a^3/(5^2 x 6^10 )
