Chapter 1.2, Problem 10SSC

To determine

The number of kilohertz in 750 megahertz.

Answer to Problem 10SSC

  $750\text{MHz}=750\times {10}^3\text{kHz}$

Explanation of Solution

Given:

  $f=750\text{MHz}$

Formula Used:

  $\begin{array}{l}1\text{kHz}{\text{=10}}^3\text{Hz}\\ 1\text{MHz}{\text{=10}}^6\text{Hz}\end{array}$

Calculations:

From the above conversion units, one can write MHz in terms of kHz.

  $\begin{array}{l}1\text{MHz}=\left({10}^3\right)\left({\text{10}}^{\text{3}}\text{Hz}\right)\\ 1\text{MHz}=\left({10}^3\right)\left(\text{kHz}\right)\\ 750\text{MHz}=750\times {10}^3\text{kHz}\end{array}$

Conclusion:

Thus, $750\text{MHz}=750\times {10}^3\text{kHz}$ .
