<PRE><B>Question 39577</B>
&lt;pre&gt;&lt;font size = 5&gt;&lt;b&gt;Multiply.

4xy&lt;sup&gt;3&lt;/sup&gt;·2x&lt;sup&gt;2&lt;/sup&gt;·5xy&lt;sup&gt;2&lt;/sup&gt;

Put a 1 exponent on the letters that don&#39;t
show an exponent

4x&lt;sup&gt;1&lt;/sup&gt;y&lt;sup&gt;3&lt;/sup&gt;·2x&lt;sup&gt;2&lt;/sup&gt;·5x&lt;sup&gt;1&lt;/sup&gt;y&lt;sup&gt;2&lt;/sup&gt;

Multiply the coefficients:  4·2·5 = 40

So far you have 40_______

Add the exponents of the x&#39;s:  1+2+1 = 4  

So far you have 40x&lt;sup&gt;4&lt;/sup&gt;_____

Add the exponents of the y&#39;s: 3+2 = 5

Now you have 40x&lt;sup&gt;4&lt;/sup&gt;y&lt;sup&gt;5&lt;/sup&gt;

That&#39;s the answer.
