Question

the display on a calculator screen is shown below.
7.703555ee-8
what number does the calculator display represent?
a. it represents 77,035,550
b. it represents 770,355,500
c. it represents 0.00000007703555

Explanation:

Step1: Recall scientific notation with EE

"EE - n" in calculator notation means multiplying by \(10^{-n}\). Here, the display is \(7.703555\text{EE}-8\), so it's \(7.703555\times10^{-8}\).

Step2: Expand \(10^{-8}\)

\(10^{-8}=\frac{1}{10^{8}} = 0.00000001\).

Step3: Multiply by 7.703555

\(7.703555\times0.00000001 = 0.00000007703555\).

Answer:

C. It represents 0.00000007703555
