Question

The diameter of a planet at its equator is 5790 kilometers.Estimate using scientific notation:

Answer 1

`5.79x10^3\text{ kilometers}`

Step-by-step explanation

Step 1

divide the number by 1000

remember:

`1000=10^3`
`(5790)/(1000)=5.79`

Step 2

input the value of cubic ten instead of 100

`\begin{gathered} 5790=5.79\cdot1000 \\ 5.79\cdot1000=5.79\cdot10^3 \end{gathered}`

then, the answer is

`5.79x10^3\text{ kilometers}`
