Answer 1

а)

$\frac{ x ^ { 3 } +y ^ { 3 } }{ (x+y) ^ { 2 } } = \frac{\left(x+y\right)\left(x^{2}-xy+y^{2}\right)}{\left(x+y\right)^{2}} = \frac{x^{2}-xy+y^{2}}{x+y}$

б)

$\frac{ am ^ { 2 } +am+a }{ m ^ { 3 } -1 } = \frac{a\left(m^{2}+m+1\right)}{\left(m-1\right)\left(m^{2}+m+1\right)} = \frac{a}{m-1}$
