Answer 1

Answer:

$= \frac{ {5}^{2} \times {x}^{ - 3} }{ {5}^{ - 3} \times {10}^{5} \times {x}^{ - 7} } \\ \\ = \frac{ {5}^{2 + 3} \times {x}^{ - 3 + 7} }{ {5}^{5} \times {2}^{5} } \\ \\ = \frac{ {5}^{5} \times {x}^{4} }{ {5}^{5} \times {2}^{5} } \\ \\ = \frac{ {5}^{5 - 5} \times {x}^{4} }{ {2}^{5} } \\ \\ = \frac{1 \times {x}^{4} }{ {2}^{5} } \\ \\ = \frac{ {x}^{4} }{ {2}^{5} }$
