Question

Please explain to me how to simplify the expression below, and what is the simplified expression?

(3x^3y^4)^2

Answer 1

I am not 100% sure because that was Pre-Algebra I learned that (i am in algebra 2) but i believe there is some square rooting in there, i just don't remember where when and why. Maybe that will jog your memory ;)

Answer 2

With (3x^3y^4)^2 you just square each term :
3^2 = 9
(x^3)^2 = x^3 x^3 = x^6
(y^4)^2 = y^4 y^4 = y^8
and now you gather together all the terms :
(3x^3y^4)^2 = 9 x^6 y^8

Does this answer look ok?
