12x^4y^8

36x^4y^5

36x^4y^8

12x^2y^7

Answer 1

Do you know the rules of exponents?

Answer 2

nope , what are they?

Answer 3

well first you expand everything which gives you

then you have to "multiply" but 1 rule says that for exponents if there is a multiplication symbol, you actually add them so you get
