$({3}^{ - 5} \times {10}^{ - 5} \times 125) \div ( {5}^{ - 7} \times {6}^{ - 5} )$

$(125 \times {5}^{7} \times {6}^{5} ) \div ( {3}^{5} \times {10}^{5} )$

$({5}^{3} \times {5}^{7} \times {6}^{5} ) \div ( {3}^{5} \times {10}^{5} )$

$( {5}^{10} \times {6}^{5} ) \div ( {3}^{5} \times {10}^{5} )$

Answer 2

Step-by-step explanation:

$\frac{ {3}^{ - 5} \times {10}^{ - 5} \times 125 }{ {5}^{ - 7} \times {6}^{ - 5 } } \\ \frac{ {3}^{ - 5} \times {2}^{ - 5} \times {5}^{ - 5} \times {5}^{3} }{ {5 }^{ - 7} \times {3}^{ - 5} \times {2}^{ - 5} } \\ = \frac{1}{ {5}^{ - 9} }$
