Question

What is 306,000,0000 in a scientific notation?

Answer 1

`3.06xx10^9`

Explanation:

The scientific notation format consists of expressing a number (normally a measurement) between 1 and 10 and then multipliying it by a whole number power of 10.

To decide on the number of digits included, find the number of significant figures present in the given number.

`3,06underbrace(0,000,000)_("trailing zeros")`
Note that the trailing zeros are not significant. This leaves your number with 3 significant figures.

This means three digits are needed in your scientific notation expression.

`underbrace (3.06xx10^9)`
