(4x^2)^3 = (4^3)*(x^2)^3

(4x^2)^3 = 64*x^(2*3)

(4x^2)^3 = 64*x^6

-------------------

(y^3)^5 = y^(3*5)

(y^3)^5 = y^(15)

-------------------------------------------------------

2(4x^2)^3 * (y^3)^5

2(64*x^6) * (y^(15))

(2*64) * x^6 * (y^(15))

128 * x^6 * y^(15)

So that's why the answer is 128x%5E6y%5E15
