Answer 2

Step-by-step explanation:

$\frac{ {8}^{ - 1} \times {5}^{3} }{ {2}^{ - 4} } \\ = \frac{ {2}^{4} \times {5}^{3} }{ {8}^{1} } \\ = \frac{ {2}^{4} \times {5}^{3} }{ { ({2}^{3}) }^{1} } \\ = \frac{ {2}^{4} \times {5}^{3} }{ {(2)}^{3 \times 1} } \\ = \frac{ {2}^{4} \times {5}^{3} }{ {2}^{3} } \\ = {(2)}^{4 - 3} \times {5}^{3} \\ = {2}^{1} \times {5}^{3} \\ = 2 \times 125 \\ = \: \: \underline{ \underline{ \large 250}}$
