also me quistion

I think you want to know real value of  this :

∛[ - 64 ] =   -4  

Hmm... I interpreted it as

\(\sqrt{-64^3}\)

In which case the answer is

\(\sqrt{-262,144}=512i\)     :)

Can't argue with you, hectictar.....it's open to interpretation.......!!!!

Wait so it's cubed... then square rooted. SO THERE IS AN " i "!
