Exercise 6 Page 345

We want to round the given decimal number and write the result as the product of a single digit and a power of 10. 899 032 878 300 Let's start by rounding the given number to the nearest 100 000 000 000. Since the digit in the ten billions place is greater than 5, we will modify the digit in the ${\color{#A800DD}{\text{hundred-}}}$${\color{#A800DD}{\text{billions}}}$ ${\color{#A800DD}{\text{place}}}.'"`UNIQ--MLMath-4-QINU`"' Finally we will write the above number as the product of a single digit and a power of10.To do so, let's first factor out9.$
