Question

Which one of the following represents 35 million in scientific notation?

Answer 1

In scientific notation, numbers are expressed in powers of 10. Looking at 35 million, it is normally written as 35000000. There are six zeros. This means that it can be written as

`\begin{gathered} 35\text{ }*10^6 \\ We\text{ can shift one more step to the left. This means that the power of 10 will increase } \\ by\text{ one. The scientific notation becomes} \\ 3.5\text{ }*10^7 \end{gathered}`
