Answer:
\(4.68\times10^9\)
Step-by-step 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 :
\(4.68\times10^9\)
We can check this if we multiply this by 10^9. This will shift the decimal to 9 places in the right side.
