Write your answer in scientific notation.

Respuesta :

[tex]\bf \cfrac{\stackrel{\textit{human hair}}{9\times 10^{-5}}}{\stackrel{\textit{spider hair}}{3\times 10^{-6}}}\implies \cfrac{9}{3}\times \cfrac{10^{-5}}{10^{-6}}\implies \cfrac{3}{1}\times \cfrac{10^{-5}10^{6}}{1} \\\\\\ 3\times 10^{-5+6}\implies 3\times 10^1[/tex]
