Evaluate if possible
3√ - 64 [cube root of -64]
= -4 (principal cube root, there are 3)
-----------------------------
and 3√ 64 [cube root of 64]
= 4 (principal cube root, there are 3)
---------------------------
and √ -64 [sqrt(-64)]
sqrt(-64) = +8i, -8i
-----------------
and √ 64 [sqrt(64) ]
= +8, -8
