Re write both numbers in same terms

[tex]\begin{gathered} 4.5\cdot10^{-24}=45\cdot10^{-25} \\ 3\cdot10^{-25} \end{gathered}[/tex]

Solve the difference

[tex]\begin{gathered} 45\cdot10^{-25}-3\cdot10^{-25}=(45-3)\cdot10^{-25} \\ (45-3)\cdot10^{-25}=42\cdot10^{-25} \end{gathered}[/tex]

4.5*10^-24-3*10^-25=42*10^-25
