You need two equals like == not one. You need brackets also and not parenthesis. Then it works. There are 4 roots by the way. Looks like you only want the real ones.

SOLVE(x^4 - 1 = 3, x) but this provides no result. Just returns the question with no answer. The answer should be x = -Sqrt(2) or x = sqrt(2). The example works in RPN, but I use both environments depending what I am doing. It worked before the upgrade. Am I missing something here! - Mike
