Question

A star has a diameter of 4,680,000,000 units. Express this number in scientific notation.

Answer 1

the answer should be 4.68x10^9. 

Answer 2

`4.68*10^9`

Explanation:

Scientific notation is defined as a way of writing very large or very small numbers.

A number between 1 to 10 is written in scientific notation when it is multiplied by a power of 10.

Here the given scenario is :

A star has a diameter of 4,680,000,000 units.

So, in scientific notation we can write this as :

`4.68*10^9`

We can check this if we multiply this by 10^9. This will shift the decimal to 9 places in the right side.
