    \[27^{-\frac{ 2 }{ 3 }} = \frac{ 1 }{ \sqrt[3]{27^2} }\]

    magic? \[\sqrt{a}=a^\frac{ 1 }{ 2 }\] similarly: \[\sqrt[100]{a}= a^{100}\] and: \[a^{-1} = \frac{ 1 }{ a^1 }= \frac{ 1 }{ a }\]

    sorry, the second one should be: \[\sqrt[100]{a} = a^\frac{ 1 }{ 100 }\]

    to be fully clear: \[\sqrt[x]{a^y} = a^\frac{ y }{ x }\]

    Just remember: the bottom number is the root, the top number is the power. So what is the third root of 27?

    Yes. The top number is the power which is 2 so what is 3 to the second power?

    I can't see very well. Is there a negative sign in front of the 2/3?
