Exercise 1 Page 353

We want to round the given decimal number and write the result as the product of a single digit and a power of 10. 0.00000129 Let's start by rounding the given number to the nearest 0.00000 1. Since the digit in the ${\color{#FF0000}{\text{ten-}}} {\color{#FF0000}{\text{millionths}}} {\color{#FF0000}{\text{place}}}is less than5,we will ''not'' modify the digit in the{\color{#A800DD}{\text{millionths}}} {\color{#A800DD}{\text{place}}}.'"`UNIQ--MLMath-3-QINU`"' Finally, we will write the above number as the product of a single digit and a power of10.$
