<PRE><B>Question 885265</B>
Place a decimal point between the first nonzero digits. Then drop the trailing zeros.


87000000


8.7000000


8.7


&lt;font color=&quot;green&quot;&gt;8.7&lt;/font&gt;


Now move the decimal point &lt;font color=&quot;blue&quot;&gt;7&lt;/font&gt; places to the right to get back to 87000000 (we&#39;re going from &lt;font color=&quot;green&quot;&gt;8.7&lt;/font&gt; to 87000000)



So that&#39;s why the final answer is &lt;font color=&quot;green&quot;&gt;8.7&lt;/font&gt; x 10^&lt;font color=&quot;blue&quot;&gt;7&lt;/font&gt;


This looks like *[Tex \Large \color{red}8.7 \times 10^{7}]</PRE>
