I have an expression that I think should be simplified to zero but Mathematica gives me a weird result. I have
Simplify[-2*Sqrt[2*a] + Sqrt[(2^3)*a]]
The result given by mathematica is
-2 Sqrt (-1 + ) Sqrt[a]
When I copied the above line of code from my notebook and pasted it here, the term appearing as
(-1 + ) looked like
(-1 + \.08). Is this of any help to solve the issue?
I'd simply like Mathematica to simplify my expression in a smart way.
EDIT: FullSimplify returns the same output
