Answer:


(1)/(√(3))

Explanation:

Evaluate:
3^{(1)/(6)} * 3^{-(2)/(3)}

Apply exponent rule:
a^b * a^c=a^(b+c)


\begin{aligned} \implies 3^{(1)/(6)} * 3^{-(2)/(3)}&=3^{(1)/(6)-(2)/(3)}\\ &=3^{-(1)/(2)\end{aligned}

Apply exponent rule:
a^(-n)=(1)/(a^n)


\implies 3^{-(1)/(2)}=\frac{1}{3^{(1)/(2)}}=(1)/(√(3))
