Chapter 9.5, Problem 61CCR

To determine

To express the numbers in the form of a single digit times an integer power of $10$ .

Answer to Problem 61CCR

The solution of $1.375\times {10}^{-43}\text{mg}\approx 1\times {10}^{-43}\text{mg}$ .

Explanation of Solution

Given information:

The given expression is:

  $1.375\times {10}^{-43}\text{mg}$

Calculation:

The solution can be obtained by:

  $\begin{array}{l}1.375\times {10}^{-43}\text{mg}\\ \approx 1\times {10}^{-43}\text{mg }\left[\text{Write the number as single digit times an integer power of 10}\right]\end{array}$

Hence, the solution of $1.375\times {10}^{-43}\text{mg}\approx 1\times {10}^{-43}\text{mg}$ .
