Question

I don’t know how to explain it.

Answer 1

`\bf ~\hspace{7em}\textit{rational exponents} \\\\ a^{( n)/( m)} \implies \sqrt[ m]{a^ n} ~\hspace{10em} a^{-( n)/( m)} \implies \cfrac{1}{a^{( n)/( m)}} \implies \cfrac{1}{\sqrt[ m]{a^ n}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ √(x^6)\implies \sqrt[2]{x^6}\implies x^{(6)/(2)}\implies x^{(3)/(1)}\implies x^3`
