Answer 1

Respuesta:

A) x + y

Explicación paso a paso:

A = (x² - xy)/x³ + y²/x³

A = (x² - xy + y²)/x³ ...(i)

B = 1 + y³/x³

B = (x³ + y³)/x³ ...(ii)

Divides (i) a (ii):

=> B/A = (x³ + y³)/x³/(x² - xy + y²)/x³ (extremos - medios)

=> B/A = (x³ + y³)(x³)/(x² - xy + y²)(x³) →se divide x³

Recordar: (x³ + y³) = (x + y)(x² - xy + y²)

=> B/A = (x + y)(x² - xy + y²)/(x² - xy + y²) → se divide (x² - xy + y²)

=> B/A = x + y
