Leaving an answer as a square root...

<p>So this is the problem I was working with
a^2 + 11^2= 16^2
a^2+ 121= 256</p>

<h2> - 121=-121</h2>

<p>a^2 = 135
a = √135</p>

<p>My question is should I leave the answer as a square root or can I just show a= 11.61 (√135= 11.61).
Let’s say a problem like this showed up on the grid-in section of the SAT, which form of the answer is better to show? Please and thank you!</p>

<p>Another question, how would I convert √44 into 2 √11 ?</p>

<p>Correct me if I’m wrong, but I don’t think a grid-in would have answers that are irrational (unless it says round to the nearest ___ or something). You can’t input the sqrt on a grid-in.</p>

<p>Also, sqrt(44) = sqrt(2^2 * 11) = 2 sqrt(11).</p>

<p>Thank you!</p>
