Question

Me ajuda por favoooor​

Answer 1

$a) \dfrac{x+y}{x} : \dfrac{x²-y² }{x}$

$\dfrac{x+y}{x} \times \dfrac{x}{x²-y²} = \dfrac{x+y}{x²-y²}$

$= \dfrac{x+y}{(x+y)(x - y)} = \dfrac{1}{(x - y)}$

$b) \dfrac{36a}{b} : \dfrac{6b²}{a³} = \dfrac{36a}{b} \times \dfrac{a³}{6b²}$

$\dfrac{36a^4 }{6b^3} = \dfrac{36}{6} \times \dfrac{a^4}{b^3}$

$\dfrac{6a^4}{b^3}$
