First, write 81 as a power, in this case, we know that the square root of 81 is 9, then,


81=9^2

then, we can rewrite the expression as:


(1)/(9^2)

since the power is at the denominator, we can write it in the numerator using a negative exponent,


\begin{gathered} 1*9^(-2) \\ \end{gathered}

Answer:


(1)/(81)=9^(-2)
