Math question

[gr8app]

<p>I got this question while doing a practice test and I actually didn't even understand what was being asked.</p>

<p>"For what positive number is the square root of the number the same as the number divided by 40?"</p>

<p>If anyone can explain it I would appreciate it.</p>

<p>Thanks</p>

<p>sqrt(x) = x / 40</p>

<p>Square both sides</p>

<p>x = x^2 / 1600
1600x = x^2
1600 = x</p>
