Round the given decimal number to the nearest 10 000 000 000.
4* 10^(10)
Practice makes perfect
We want to round the given decimal number and write the result as the product of a single digit and a power of 10.
38 108 996 999
Let's start by rounding the given number to the nearest 10 000 000 000. Since the digit in the billions place is greater than 5, we will modify the digit in the ${\color{#A800DD}{\text{ten-}}}$${\color{#A800DD}{\text{billions}}}$ ${\color{#A800DD}{\text{place}}}.'"`UNIQ--MLMath-4-QINU`"'
Finally, we will write the above number as the product of a single digit and a power of10.To do so, let's first factor out4.$
