Question

Please help as fast as you can I need this turned in today

Answer 1

we have the following:

`(5\cdot10^(-3)+6\cdot10^(-3))/(2.2\cdot10^4)`

operating:

`\begin{gathered} (5\cdot10^(-3)+6\cdot10^(-3))/(2.2\cdot10^4)=(11\cdot10^(-3))/(2.2\cdot10^(-4))=(1.1\cdot10^(-2))/(2.2\cdot10^(-4))=0.5\cdot10^(-2-4)=0.5\cdot10^(-6) \\ =5\cdot10^(-7) \end{gathered}`

Theerefore, the answer is the first option
