Question

the oregon department of education budget for the 2019-2021 biennium was $4,054,402,710. write this number in scientific notation.

Answer 1

Scientific notation is a way to write very large or very small numbers so that they are easier to read and work with. This is done by expressing a number as the product of a number greater than or equal to 1 but less than 10 and an integral power of 10.

The number in the question is given to be:

`$4,054,402,710$`

If we were to move the decimal point at the end of the number to the position behind 4, we will have the number as shown below:

If we count the number of places we move the decimal place, it is 9 places:

Therefore, the number in scientific notation is:

`4.05*10^9`
