Answer:
To write 291,000,800 in scientific notation, we need to follow these steps:
Move the decimal point 8 places to the left to get 2.910008. This is the number a that is between 1 and 10.
Count how many places we moved the decimal point. This is the number b that is the power of 10. Since we moved the decimal to the left, b is positive. b = 8
Write the number as a x 10^b and read it as “a times 10 to the power of b”. The number 291,000,800 in scientific notation is 2.910008 x 10^8
I hope this helps you understand how to write numbers in scientific notation.
