Question

How do you write $2.5$ million in scientific notation.

Answer 1

Convert to scientific notation

Given, $2.5$ million $=2,500,000$.

$\begin{array}{rcl}2,500,000& =& 2.5\times 1,000,000\\ & =& 2.5\times {10}^6\end{array}$

Hence, $2.5$ million is written as $2.5\times {10}^6$ in scientific notation.
