Answer 1

Resolvendo:

$\frac{9\:.\:10^{9}\:.\:(0,0001)^{-2}\:.\:2\:.\:10^{-4} }{(0,001)\:.\:18\:.\:10^{-5}\:.\:(0,01)\:.\:1000 } =\\\\\\\frac{9\:.\:10^{9} \:.\:(10^{-4})^{-2} \:.\:2\:.\:10^{-4} }{10^{-3}\:.\:18\:.\:10^{-5} \:.\:10^{-2} \:.\:10^{3} } =\\\\\\\frac{18\:.\:10^{9} \:.\:10^{8}\:.\:10^{-4} }{18\:.\:10^{-3} \:.\:10^{-5}\:.\:10^{-2} \:.\:10^{3} } =\\\\\\\frac{10^{9+8-4} }{10^{-3-5-2+3} } =\\\\\\\frac{10^{13} }{10^{-7} } =\\\\10^{13-(-7)} =\\\\\\10^{20}$

Espero ter ajudado!
