<p>Barron's says this:</p>
<p>2^3=p^3x3
8 =p^3x3
= p^9
hence, 8p=9^p x p = p^10</p>
<p>Why do you multiply by the extra p?</p>
<p>Thanks for the help. Also, please don't make fun of me, my 600 is enough to tell me I suck at math.</p>
<p>since 8 = p^9</p>
<p>It follows that 8p = p^10</p>
<p>Why? I still don't get how that connects, sorry. </p>
<p>In return, I'll answer any question you have about grammar :/</p>
<p>8=p^9</p>
<p>multiply both sides by p----->8p=p^9*p^1=p^9+1=p^10</p>
<p>which part is not clear?</p>
<p>8=p^9 You understood till here right?
The secret of SAT maths is to get what you need from anything or everything given to you
Now the question asks......what is 8p
Given,
8=p^9
how do we get 8p
simple,,multiply both sides with p
(8)<em>p= (p^9)</em>p
or, 8p=p^10</p>
<p>You could also express 8p as 4p^4,</p>
<p>Since 2 = p^3, 8 = 4xp^3, so 8p is 4p^4. That's just as good.</p>
<p>God, I'm dense. Thanks isnwta.</p>
<p>Anytime,,</p>
