Question regarding (-8)^(2/3) #567
When putting the expression of (-8)^(2/3) into my TI-84 calc, I get a result of 4. Another example is (-8)^(1/3), which should evaluate to -2. However, I am getting a different results on MathJS.
When you get a free moment, would you help me with this.
Great readings. How would you suggest me to apply the .cbrt() function to evaluate the (-8)^(2/3) or (-8)^(-2/3) when to the power of is other than 1/3? The .eval() handles the (8)^(2/3) great, but I've noticed that when negative numbers are included such as (-8)^(2/3) or (-8)^(-2/3) then I get complex answers back.
