Quartic equation problem in Maple

Question

I'm having this problem when trying to solve this equation in Maple.

$f(x) = x^{4}-27.9000678$

Here's the error

Each time i try to run the solve command Maple returns me this weird answer: proc (x) 1/10*RootOf(500*_Z^4-139500339,label = _L3) end proc

Is this related to my software or could it be a bug within the program? Can you experts please help me to bypass this or suggest me an alternate solution?. Thanks in advance.

Answer 1

The issue is with how you have f declared. If you want f to be a function, use:

f := x -> x^4 - 27.9000678;
solve(f(x)=0,x);

This returns:

2.298271411, 2.298271411*I, -2.298271411, -2.298271411*I

Otherwise if you use your code (where f is declared as a variable) then the following will work:

f:=x^4-27.9000678;
solve(f=0,x);
