<p>here's the question i'm confronted with:</p>

<p>log^2 (n)</p>

<p>is this the same thing as</p>

<p>log (log (n))</p>

<p>or</p>

<p>(log(n))^2 ???</p>

<p>ah . never mind. i got it.</p>

<p>Do you mean</p>

<p>log (n)^2 = 2log (n)</p>

<p>?</p>

<p>it seems like the whole thing is supposed to be squared, like with sin, cos, etc the proper notation is to place the exponent before the "inside" of the function like sin^2(x) + cos^2(x) = 1</p>

<p>otherwise if you write something like sin x ^2 + cos x ^2 it could look like the inside (the "x" in this case) is being squared.</p>
