​

Answer 1

Answer:

$\frac{1}{2^{40} }$

Step-by-step explanation:

$(5^{-1-19})^{2} (\frac{5}{2})^{40} \\(5^{-20})^{2}(\frac{5^{40} }{2^{40}}) \\(\frac{1}{5^{20} } )^{2} (\frac{5^{40} }{2^{40}})\\(\frac{1}{5^{20(2)} })(\frac{5^{40} }{2^{40}})\\(\frac{1}{5^{40} })(\frac{5^{40} }{2^{40}})\\\frac{5^{40} }{5^{40}(2^{40}) } \\\frac{1}{2^{40} }$
