case a) [tex]0.00037[/tex]
we know that
[tex]0.00037=\frac{37}{100,000} =\frac{37}{10^{5}} =37*10^{-5}[/tex]
[tex]37*10^{-5}=(3.7*10)*10^{-5}=3.7*10^{-4}[/tex]
therefore
the answer Part a) is
[tex]3.7*10^{-4}[/tex]
case b) [tex]37,000[/tex]
we know that
[tex]37,000=37*1,000 =37*10^{3}=(3.7*10)*10^{3}=3.7*10^{4}[/tex]
therefore
the answer Part b) is
[tex]3.7*10^{4}[/tex]
