Find the product of this expression.

(12x 3 y 2) 2 3x 2 y =
this is what i got
(i) (aⁿb^o)^d = a^(nd)b^(od)
(ii) aⁿ * a^b = a^(n + b)

Expand (12x³y²)² by Formula (i):

12²x^(3*2)y^(2*2) * 3x²y
= 144x^6y^4 * 3x²y

Then, since you are multiplying terms, add up the exponents of the same bases by Formula (ii):

144x^6y^4 * 3x²y
= 144x^(6 + 2)y^(4 + 1)
= 144x^8y^5
but i am doing online and the answer saids it should be
-3-x---????help anyone i am doing polynominals thanks danke
