Answer 1

Explicación paso a paso:

8.

$\frac{ {a}^{5} }{ {a}^{3} } + \frac{2 {a}^{10} }{ {a}^{8} } + \frac{ {a}^{15} }{ {a}^{13} } \\ \\ = {a}^{5 - 3} + 2 {a}^{10 - 8} + {a}^{15 - 13} \\ \\ = {a}^{2} + 2 {a}^{2} + {a}^{2} \\ \\ = 4 {a}^{2}$

9.

$- ( - 2 {x}^{6} ) \times - ( - 3 {x}^{4} )( - 2 {x}^{2} ) \\ \\ = (2 {x}^{6} )(3 {x}^{4} )( - 2 {x}^{2} ) \\ \\ = - 12 {x}^{12}$
