<PRE><B>Question 381181</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;There are several different ways to simplify this expression. &lt;br&gt;

The easiest way is to multiply the regular numbers, and then multiply the exponential numbers.&lt;br&gt;

So we should have:&lt;br&gt;

{{{(2*2)*(10^4*10^8)}}}&lt;br&gt;

{{{4*10^12}}}&lt;br&gt; 

because when you multiply exponents with the same base, you just add the exponents.&lt;br&gt;

You can also do this on a calculator or by hand.&lt;br&gt;

{{{(2*10000)*(2*100000000)}}}&lt;br&gt;

{{{20000*200000000}}}&lt;br&gt;

{{{4000000000000}}}&lt;br&gt;

Notice that we end up with 4 with 12 zeros after it?&lt;br&gt;

That is numerically identical to {{{4*10^12}}}&lt;br&gt;

I hope this helps!&lt;br&gt;</PRE>
