What is the description of simply squaring roots?

Simply squaring roots involves taking numbers that are under square roots and squaring them individually. When you have a square root, such as √a, squaring it would simply yield a, which means that you're reversing the square root operation.

Therefore, when you square the individual numbers under each root, you essentially get back to the original numbers before they were placed under the square root. For example, if you have √x and √y, squaring them would give you x and y respectively. Thus, you are handling each root independently by squaring the values under them.

The other options do not capture this process accurately. Taking an average or dividing and taking a square root involves different operations that do not pertain to simply squaring the values under the roots. Multiplying square roots together relates to a different aspect of square roots and does not represent the action of squaring them. Thus, the accurate understanding of squaring the roots is captured in the option that refers to squaring the individual numbers beneath each square root.
