Answer 1

Explicație pas cu pas:

a)

$\dfrac{^{x)} 1}{x} = \dfrac{x}{x^{2}} \ , \ \dfrac{1}{x^{2}}$

b)

$\dfrac{^{3)} 3}{2y} = \dfrac{9}{6y} \ , \ \dfrac{^{2)} -4}{3y} = \dfrac{ -8}{6y}$

c)

$\dfrac{^{4)} 1}{9x^{2}} = \dfrac{4}{36x^{2}} \\ \dfrac{^{3x)} 5}{12x} = \dfrac{15x}{36 {x}^{2} } \\ \dfrac{^{2x)} 1}{18x} = \dfrac{2x}{36 {x}^{2}}$

d)

$\dfrac{^{3xy^{2})} a}{8x^{2}y} = \dfrac{3axy^{2}}{24x^{3}y^{3}} \\ \dfrac{^{4 {x}^{2} )}5b}{6xy^{3}} = \dfrac{20b {x}^{2} }{24 {x}^{3} y^{3}} \\ \dfrac{^{8y^{3})}c}{3x^{3}} = \dfrac{8c {y}^{3} }{24x^{3}y^{3}}$
