I believe the answer is an average of 4800 beats per hour.
We know that the heart beats an average of 80 beats per minute and there are 60 minutes in an hour. We can use this information and multiply 80x60 to find the average amount of heartbeats in an an hour.

Given :-

$(9^{2} )^{-1/3}$

To Find :-

To solve the expression .

Solution :-

Given expression to us is ,

$(9^{2} )^{-1/3}$

We know that ,

$9 = 3^2$

So our expression becomes ,

$\{ (3^2)^2\}^{\frac{-1}{3}}$

And , $(a^m)^n =a^{mn}$ . Using this ,

$(3^4)^{\frac{-1}{3}}$

Again using the same law ,

$3^{\frac{-4}{3}}$

We know that , $a^{-m}=\frac{1}{a^m}$ . Therefore ,

$(3^{-4})^{\frac{1}{3}}$

$\\\bigg( \dfrac{1}{3^4}\bigg)^{1/3}$

$\\ \dfrac{1}{\sqrt[3]{3^4}}$

Simplify ,

$\dfrac{1}{3\sqrt[3]{3}}$

This is the simplified expression.
