Solution:-

 \implies   \frac{ \cancel{3 { }^{ - 5}}  \times 10  {}^{ - 5} \times 5 {}^{3}  \times 7 {}^{2} }{5 {}^{ - 7}  \times 2 {}^{ - 5}  \times  \cancel{3 {}^{ - 5}}  \times 7  {}^{3} \times 5  {}^{2} }  \\  \\  \\  \implies \:  \frac{ \cancel{2 {}^{ - 5}} \times 5 {}^{ - 5} \times 5 {}^{3}  \times 7 {}^{2 - 3}   }{5 {}^{ - 7 + 2} \times  \cancel{2 {}^{ - 5}}  }  \\  \\  \\  \implies \:  \frac{ \cancel{5 {}^{ - 5}} \times 5 {}^{3}   \times 7 {}^{ - 1} }{ \cancel{5 {}^{ - 5} }}  \\  \\  \\  \implies \:  \frac{125}{7}  \\  \\   \\  \implies \: 17.85

formula uses

 \implies \pink{a {}^{m} .a {}^{n} = a {}^{ m+ n}  } \\  \\  \\  \implies \pink{  \frac{a {}^{m} }{a {}^{n} } = a {}^{m - n}   }

Answer:

 \frac{{3}^{ - 5}  \times {10}^{ - 5}  \times   {5}^{3} \times   {7}^{2}  }{{5}^{ - 7} \times  {2}^{ - 5}  \times  {3}^{ - 5}  \times  {7}^{3} \times  {5}^{2}   }

 \frac{ {2}^{ - 5}   \times {5}^{ - 5} \times 5 }{ {5}^{ - 7} \times  {2}^{ - 5}  \times 7 }

 \frac{ {5}^{2} \times 5 }{7}

 \frac{ {5}^{3} }{7}

or

 \frac{125}{7}
