Solving a simple equation, is it normal?
I was trying to solve the first equation from the pic with HP Prime (latest firmware).
But solution never came out. However, the second one (simply changed variable's location) works. Unless the numbers on an equation are small, it works fine. (eg. solve(10=5/pi*x^2)) If anyone could tell me why this happened, it would be very helpful for me. Thanks. *same equation: http://www.wolframalpha.com/input/?i=sol...12*x%5E2)

RE: Solving a simple equation, is it normal? (need help)
For one thing, the CAS solve() command works with polynomials, or a set of polynomials.
The first equation you were trying to solve, isn't a polynomial.

or just use exact; keep your eye on epsilon
solve((262144/86802649006623) = (1/38965026550769497442385943030554165248/((1/8991804694)*x^2)))
