<p>What is the sqrt of 16?</p>
<ul>
<li>or - 4</li>
</ul>
<p>is that a trick question?</p>
<p>square root of 16 = |4| = 4</p>
<p>Anonymous gets a 0%, kchen gets a 100%. Those scores WILL be reported to colleges by me, so please let me know what schools you are applying to so I can email them.</p>
<p>EDIT: I meant the other way around, anonymous gets a 100 and kchen a 0.</p>
<p>haha....wow; i should have known...I won't delete my post...i don't care if people laugh at me!</p>
<p>report me to Harvard please!</p>
<p>EDIT here too!</p>
<p>Never mind what I just wrote! Report me to Yale now!</p>

<p>Yes kchen but -4^2 is also 16, as that wikipedia says. "There are two solutions to the square root of a non-zero number. For a positive real number, the two square roots are the principle square root and the negative square root." Sorry but you get a 0 reported to your school.</p>
<p>"In mathematics, the principal square root of a non-negative real number x is denoted (sqrt sign here) and represents the non-negative real number.."</p>
<p>If the problem is just sqrt(x), only the positive number is the answer.</p>
<p>No sir, it's postive and negative. The principal sqrt is the non-negative but the general sqrt answer is positive or negative.</p>
<p>and the question is worded asking for the general sqrt ;)</p>
<p>Weird... and incredibly pretentious. Have fun!</p>
<p>(I vote for kchen!!!!!)</p>
<p>Psh, how was I supposed to know what kind of square root you were talking about? Haha.</p>
<p>Thanks for the support, theoneo.</p>
<p>Only on CC would something like this even be debated though.</p>
<p>Anytime, kchen.</p>
<p><3</p>
<p>And actually we've debated that in like half my math classes since seventh grade or so.</p>
<p>Yeah, I debated this with my dad a couple of years ago, so I really don't want to start another one.</p>
<p>you all know that the teacher is always right even if he/she is wrong!</p>
<p>just accept that logisticswizard has the right answer and that my answer is right ;)</p>
