What is wrong??
2/6 is equal to 1/3 and we have :
(-1)^(2/6)=((-1)^2)^ 1/6=1 and
(-1)^(1/3)=-1
what is wrong??
Answer:
You have wrongly applied a property, which is the commutative property for exponents.
You originally had (-1) raised to something.
You can pass the exponent to inside of the brackets, but, in this case, it goes to the top of the 1 you had.
If you want to keep the brackets, then you would have 2*1/6, not 2^(1/6): They are different things.
