$\frac{5 {}^{ - 3} \times 10 {}^{ - 5} \times 625 }{ {2}^{ - 7} \times 50 {}^{2} } \\ = \frac{ {5}^{ - 3} \times 10 {}^{ - 5} \times 5 {}^{4} }{ {2}^{ - 7} \times (10 \times 5){}^{2} } \\ = \frac{5 {}^{ - 3 + 4} \times 10 {}^{ - 5} }{ {2}^{ - 7} \times 10 {}^{2} \times 5 {}^{2} } \\ = {5}^{1 - 2} \times {2}^{7} \times 10 {}^{ - 5 - 2} \\ = {5}^{ - 1} \times 2 {}^{7} \times 10 {}^{ - 7} \\ = \frac{ {2}^{7} }{5 {}^{1} \times 10 {}^{7} } \\ = \frac{128}{5 \times 10 {}^{7} }$
