<p>How do you solve this problem?</p>

<p>.......................sqrt(x)<br>

<--l--l--l--l--l--l--l--l--l--l-->
....0.............................1 </p>
<p>On the number line above, there are 9 equal intervals between 0 and 1. What is the value of x?</p>
<p>The answer is 4/9.</p>
<p>Nevermind; there’s no need to answer this! I figured it out.</p>
<p>Well I haven’t. Basically it should be 6/9 isn’t it ?</p>
<p>Bassplayer, they’re trying to trick you… as always.</p>
<p>They want you to believe it’s 6/9 but that’s not right.</p>
<p>It’s really…</p>
<p>sqrt(x) = 6/9</p>
<p>Simplify: sqrt(x) = 2/3</p>
<p>Now square both sides: sqrt(x)^2 = (2/3)^2</p>
<p>Answer: x = 4/9</p>
<p>Oh, OK thanks
lol I just read x and not sqrt(x) (obviously what they wanted me to do).</p>
