 \bf{ \frac{a + 1}{a + 2}  = 0} \\  \\  \bf{ \rightarrow \: a + 1 = 0 \times (a + 2)} \\  \\  \bf{ \rightarrow \: a + 1 = 0}  \\  \\   \bf{ \rightarrow \: x =  - 1}




Hence,


 {(a + 2)}^{3}  +  \frac{1}{ {(a + 2) }^{3} }  \\  \\  =  >  \mathbf{( - 1 + 2) ^{3}  +  \frac{1}{ {( - 1 + 2)}^{3} } } \\  \\  \\   =  >   \bf{{1}^{3}  +  \frac{1}{ {1}^{3} }}  \\  \\  =  >  \bold{1 + 1} \\  \\  \bold{ =  > 2}
