Round the given number to the nearest 1 000 000 000.
8* 10^9
Practice makes perfect
We want to round the given number and write the result as the product of a single digit and a power of 10.
8 031 426 100Let's start by rounding the given number to the nearest 1 000 000 000. Since the digit in the hundred millions place is less than 5, we will not modify the digit in the billions place.
8 031 426 100 ≈ 8 000 000 000
Finally we will write the above number as the product of a single digit and a power of 10. To do so, let's first factor out 8.
