How is 26.5 billion written in scientic notation?

Answer 1

26.5 billion can be written in scientific notation as 2.65 x 10^10. This is because the decimal point is moved 10 places to the left to convert the number to a value between 1 and 10, and 10 raised to the power of 10 represents the original value of 26.5 billion.

Answer 2

In scientific notation there should be a single digit before the decimal point

So you need to write 2.65 times 10 to the power of something

26.6 billion is normally written 26,500,000,000, count the digits after the 2, there are 10 of them

So you need to write 2.65 x 1010
