The process of removing roots from the denominator of fractions is called what?
- Rationalizing the denominator.

- Derooting the denominator.
Explanation from PART66Online
Removing a root (surd) from the denominator of a fraction is called rationalising the denominator, usually done by multiplying top and bottom by a suitable surd. The aim is to leave the denominator as a rational number. The other terms listed are not standard mathematical names for this process.

Hello.
Maybe you didn't read question correctly. In this case answer is "Rationalizing the denominator". Check this link: purplemath.com/modules/radicals5.htm
Squaring not correct in this case.
