Evaluate $3^{-2} imes 27^{\frac{2}{3}}$

Question

Evaluate $3^{-2} 	imes 27^{\frac{2}{3}}$

Accepted Answer

1. $3^{-2} = \frac{1}{9}$ and $27^{\frac{2}{3}} = (3^3)^{\frac{2}{3}} = 3^2 = 9$. Multiplying gives $\frac{1}{9} 	imes 9 = 1$. Distractors arise from sign errors or misapplication of the fractional exponent.
