Question

How do you write $13$ million in scientific notation?

Answer 1

Express the given number in scientific notation:

The given number: $13$ million.

$13$ million is written as $13,000,000$.

$$\begin{gathered} \Rightarrow 13,000,000=1.3\times 10,000,000 \\ \Rightarrow 13,000,000=1.3\times {10}^7 \end{gathered}$$.

Therefore, the $13$ million can be expressed in scientific notation as $1.3\times {10}^7$.
