A sugar ant is approximately 2 × 10^−3 meters long. If you put 10 million sugar
ants in a line, what is the distance from end to end?
 200 meters
 2,000 meters
 20,000 meters
 200,000 meters

&lt;font size = 4&gt;&lt;font color = blue&gt;&lt;b&gt; 2 x 10&lt;font color = red&gt;&lt;b&gt;&lt;sup&gt;- 3&lt;/font&gt;&lt;/font&gt;&lt;/b&gt;&lt;/sup&gt; &lt;font size = 4&gt;&lt;font color = blue&gt;&lt;b&gt; x 10,000,000&lt;/font&gt;&lt;/b&gt;
&lt;font size = 4&gt;&lt;font color = blue&gt;&lt;b&gt; 2 x 10&lt;/font&gt;&lt;/font&gt;&lt;font color = red&gt;&lt;sup&gt;- 3&lt;/font&gt;&lt;/font&gt;&lt;/sup&gt;&lt;font size = 4&gt;&lt;font color = blue&gt;  x 10&lt;font color = red&gt;&lt;sup&gt;7&lt;/font&gt;&lt;/font&gt;&lt;/b&gt; --- Converting 10,000,000 to EXPONENT with base 10
&lt;font size = 4&gt;&lt;font color = blue&gt;&lt;b&gt; 2 x 10&lt;font color = red&gt;&lt;b&gt;&lt;sup&gt;(- 3 + 7)&lt;/font&gt;&lt;/font&gt;&lt;/b&gt;&lt;/sup&gt; ----- Adding EXPONENTS, when multiplying same base
&lt;font size = 4&gt;&lt;font color = blue&gt;&lt;b&gt; 2 x 10&lt;font color = red&gt;&lt;b&gt;&lt;sup&gt;4&lt;/font&gt;&lt;/font&gt;&lt;/sup&gt; = &lt;font size = 4&gt;&lt;font color = blue&gt;2 x 10,000 = &lt;font color = green&gt;20,000 meters&lt;/font&gt;&lt;/font&gt;&lt;/b&gt;&lt;/pre&gt;</PRE>
