Answer:
S = √(3V/H)
Explanation:
The opposite operation of squaring is taking the square root.

_____
In the more general sense, the inverse operation for raising to a power is raising to the reciprocal of that power. We know that ...
(a^b)^c = a^(bc)
When we want bc=1, we must have c=1/b.
We know that the denominator of a fractional power is the index of the corresponding root:
![\displaystyle x^(1)/(n)=\sqrt[n]{x}](https://img.qammunity.org/2021/formulas/mathematics/college/9nyv1tfrldzh6moepf5rzzaozu3zxfd18k.png)
For n=2, we don't usually write the index in the root symbol:

In the case of this problem, ...
