Question

fernando factored 45y^6 as (9y^3)(5y^3). salma factored 45y^6 as (3y)(15y^5). which of them factored 45y^6 correctly? choose 1 answer: a only fernando b only salma c both fernando and salma d neither fernando nor salma

Explanation:

Step1: Multiply Fernando's factors

$(9y^{3})(5y^{3})=9\times5\times y^{3 + 3}=45y^{6}$

Step2: Multiply Salma's factors

$(3y)(15y^{5})=3\times15\times y^{1+5}=45y^{6}$

Answer:

C. Both Fernando and Salma
