Chapter 4.4, Problem 29IP

To determine

To find: the distance inscientificnotation.

Answer to Problem 29IP

The distance in scientific notation is $3.84\times {10}^8\text{meter}$ .

Explanation of Solution

Given information:

Thedistance is $3.84\times {10}^5$ kilometers.

Calculation : to find the scientific notation, it is needed to convert kilometer into meters so first substitute then move the decimal point, the decimal exponent is positive,

  $\begin{array}{l}3.84\times {10}^5\text{kilometer}=3.84\times {10}^5\times 1000\text{ [1kilometer=1000meter]}\\ 3.84\times {10}^5\text{ kilometer}=3.84\times {10}^8\text{meter [ move the decimal point 3 places]}\end{array}$

Thus, the distance is $3.84\times {10}^8\text{meter}$ .
