Chapter 7 - Exponents and Exponential Functions - 7-2 Scientific Notation - Lesson Check: 7

Answer

$\{3.5\times10^{6},3.6\times10^{6},2.1\times10^7,2.5\times10^{7}\}$

Work Step by Step

To order numbers in scientific notation, we first must write each number in scientific notation. $\{2.5\times10^{7},2.1\times10^7,3.5\times10^{6},3.6\times10^{6}\}$ Then, we order the numbers first by their powers of $10$. For numbers with the same power of $10$, we arrange them by their decimal parts. $\{3.5\times10^{6},3.6\times10^{6},2.1\times10^7,2.5\times10^{7}\}$
