Chapter 9.5, Problem 57CCR

To determine

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

Answer to Problem 57CCR

The solution of $0.00000035\text{cm}\approx 3.5\times {10}^{-7}\text{cm}$ .

Explanation of Solution

Given information:

The given expression is:

  $0.00000035\text{cm}$

Calculation:

The solution can be obtained by:

  $\begin{array}{l}0.00000035\text{cm}\\ =\frac{3.5}{{10}^7}\left[\text{Write the number as fraction}\right]\\ \approx 4\times {10}^{-7}\text{cm }\left[\text{Write the number as single digit times an integer power of 10}\right]\end{array}$

Hence, the solution of $0.00000035\text{cm}\approx 3.5\times {10}^{-7}\text{cm}$ .
