<h2>Cubing both sides of an equation is reversible.</h2>Step-by-step explanation:
Squaring both sides of an equation is irreversible, because the square power of negative number gives a positive result, but you can't have a negative base with a positive number, given that the square root of a negative number doesn't exist for real numbers.
In case of cubic powers, this action is reversible, because the cubic root of a negative number is also a negative number. For example
We cube both sides
If we want to reverse the equation to the beginning, we can do it, using a cubic root on each side
There you have it, cubing both sides of an equation is reversible.
