Chapter 4.5, Problem 21IP

To determine

To evaluate : the expression

Answer to Problem 21IP

The solution of the expression in scientific notation is $2.144\times {10}^8$

Explanation of Solution

Given information :

The expression is $\left(2.764\times {10}^8\right)-\left(6.2\times {10}^7\right)$

Calculation :

The value of the expression is:

  $\begin{array}{l}\left(2.764\times {10}^8\right)-\left(6.2\times {10}^7\right)\\ \left(27.64\times {10}^7\right)-\left(6.2\times {10}^7\right)\\ \left(27.64-6.2\right)\times {10}^7\\ 21.44\times {10}^7\\ 2.144\times {10}^8\end{array}$

Hence, the solution of the expression in scientific notation is $2.144\times {10}^8$
