Why is 5-⅔ (5 raised to the power of -2/3) equal to 1/5⅔ (1 divided 5 raised to the power of 2/3)? I mean to say how does the negative sign of the exponent ⅔ change to positive when 5-⅔ (5 raised to the power of -2/3) is inversed?

I wouldn't say "It's just obvious". When you have , it means . When the exponent, which means the number of 5s you multiply the 1 by is negative, you start dividing. Therefore,
