Remark

An anion is a charged ion that has taken on electrons. So you are talking about an activity that definitely involves electrons. It would seem reasonable to believe that the increase in the size of an ionic radius is caused by an increase in the number of electrons in the valence (outside) ring. The statement is true.

Hey! :)

Some things to note: When you bring a exponent to the numerator, you make it negative.

When you put an exponent to another exponent, you multiply the exponents together.

(\frac{3x^2y^5}{x^6y^2} )^4\\\frac{81x^8y^{20}}{x^{24}y^8}\\81x^8x^{-24}y^{20}y^{-8}\\\frac{81y^{12}}{x^{16}}

so that is your answer, please let me know if you need more of an explanation. :)
