Try 1.14121356237^2, where ^2 is the x2 (x squared) key.  This, of course, only
works for square roots, not cube or 4th roots, etc.

For problems like 4.242650687 = 3*sqrt(2), when you use this method, you get
18.  This is because 3*sqrt(2) = sqrt(18), so if you want to factor out any
squares, you should write a program to do that (unless the 86 can do it).  But
the answer is correct, even if it isn't in the preferred form.
