Addition and Multiplication Correspondence

Into which column (addition or multiplication) would each property fall? Write the corresponding property that would go in the other column.

a. x^m/x^n=x^(m-n)
b. a(b+c)=ab+ac
c. p^(1/n)*q^(1/n)=(pq)^(1/n)
d. The geometric mean of p and q is (pq)^(1/2)
e. (p-q)-(r-s)=(p-q)+(s-r)
f. (x^5*y*z^4)/(x*y*z^6)=x^4/z^2=x^4*z^-2

What does it mean for a property (i.e., an equation) to fall into (the column of) addition (or multiplication)?

I just join this forum today it self and really appreciate your work.All you have explained is properties like associativity etc.household moving companies
