Which of the following is equivalent to the expression (9x^2y^3) (12x^-3y^5) (2xy)
A: 23x^-5y8
B: 216y^9
C: -x^-6y^8
D: -216x^-7y^15
A little math question I had for homework I couldn't solve. Any help?
(9x^2y^3) (12x^-3y^5) (2xy) → (9*12*2)*(x^2*x^-3*x)*(y^3*y^5*y) → 216*(x^[2-3+1])*(y^[3+5+1]) → 216*x^0*y^9 → 216*y^9
