Answer 1

The given expression is :

`(7.2*10^(-6))+(5.44*10^(-6))`

The multilpy are same So, we take the 10^(-6) Common

`\begin{gathered} (7.2*10^(-6))+(5.44*10^(-6)) \\ (7.2*10^(-6))+(5.44*10^(-6))=10^(-6)(7.2+5.44) \\ (7.2*10^(-6))+(5.44*10^(-6))=10^(-6)(12.64) \\ (7.2*10^(-6))+(5.44*10^(-6))=12.64*10^(-6) \end{gathered}`

Answer:

`(7.2*10^(-6))+(5.44*10^(-6))=12.64*10^(-6)`
