Answer:
1) [tex]2.406e^{-4}[/tex]
2) [tex]-5.618e^{-19}[/tex]
3) [tex]-2.14275e^{-16}[/tex]
Step-by-step explanation:
1) First you need to reorder the terms, to do a simple sum:
(61 x 10⁻⁷) + (2.25 x 10⁻⁵) + (212.0 x 10⁻⁶) =
[tex]6.1e^{-6} + 22.5e^{-6} + 212e^{-6}=[/tex]
Now you can simply sum each term, because the exponential is the same:
[tex]240.6e^{-6}=\\ 2.406e^{-4}[/tex]
2) First you need to reorder the terms, to do a simple sum:
( ― 54 x 10⁻²⁰ ) + ( ― 2.18 x 10⁻¹⁸ ) =
[tex]-5.4e^{-19} - 0.218e^{-19}=[/tex]
Now you can simply sum each term, because the exponential is the same:
[tex]-5.618e^{-19}[/tex]
3) First you need to reorder the terms, to do a simple sum:
( ― 21.46 x 10⁻¹⁷ ) ― ( ― 3,250 x 10⁻¹⁹ ) =
[tex]-21.46e^{-17} + 0.0325e^{-17}=[/tex]
Now you can simply sum each term, because the exponential is the same:
[tex]-21.4275e^{-17}=\\-2.14275e^{-16}[/tex]
