I added a screenshot of the complete question.


True

Explanation:
Rules of the root are as follows:


Now the given is:

This rule is the same as the first rule mentioned above, therefore, it is correct.
We use this rule to convert roots into powers which facilitates solving the problems given

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
